One thing I will also suggest is that you can use BOTH an Arduino and a Pi. In a project I'm working on, I'm letting the Arduino be the powerhouse for I/O interactions with sensors and transmit the data back via Serial to the PI, who is acting as a Websocket server for other things to connect to as well as handling other math computations on the sensor's data, leaving the Arduino to only worry about managing sensors. Because the Arduino IDE is even available on the Raspberry Pi, you can have a fully set up development kit ready and on standby.
One thing you didn't touch on is the fact that the Raspberry Pi is not a real-time system. Because it runs a full OS, when you delay 1000 ms, you may get a delay of 1010 ms instead. Not a big deal, but it does add up in the long run. The Arduino platform, on the other hand is a real-time system. 1000 ms means 1000 ms. (Real-time might not be the correct term here.)
Rick Seiden if using the Rpi os then yes, but there are other options available. I heard about a real-time Linux Kernel and other small but yet usable operative systems made for rt applications
nope. The Linux kernel schedules tasks and threads for multitasking, you can't use it as a single-task real-time environment. The only way to obtain the same degree of control over hardware that you get with an Arduino is running your program after the bootloader with no OS.
I didn't know there was a real-time Linux Kernel. Actually, as Paul-Adrian Stoleriu says below, I didn't think it was possible to have one. I'm not saying they don't exist, just that I didn't know about them. I've made some great projects with my Raspberry Pis, and the real-time issue never came up, because I didn't rely on it for those projects.
I have been watching your channel for the last two weeks, after taking a hiatus from electronics for a few years. Literally any topic I can think of you have already done an excellent video on!
I like both. I used to use kernel modules for timing with sysfs to interact with user space, but now I use an Arduino to provide a software and hardware abstraction layer that simplifies development and protects my much more expensive raspberry pi from electrical damage.
Please do a project using Raspberry Pi and Arduino together. Arduino GPIO with the brains of the Pi would be cool. Maybe an irrigation system where you can access a web server front end to control, or something similar?
Why adding a 8-bit controller to a 32/64-bit ARM core(s) with plenty of RAM? When you want to do, for example, just add a PCA9685 : github.com/vanvught/rpidmx512/tree/master/lib-pca9685
I accidentally notice that almost everytime that you start speaking, you inhale so hard like if you were breathless And now I can't unnotice... ... nor you all
The GPIO can definitely be awesome for getting started with simple hardware development that also involves a software-in-an-OS side. But for things that need a lot of GPIO stuff and not really a complete operating system, I'd directly use a Microcontroller like an Arduino, or an ESP if you want a bit of networking as well. I personally use the GPIO more like a custom pin header to include things like fan control and a power button and LED, perhaps also for sensors in the future (though only if it's really stationary and requires to run with an OS).
Two projects I have always wanted to see done with a RPI...solar panel alignment system using solar tracking (panel follows the sun for max power) and similar auto window blind adjustment to most efficiently adjust vertical blinds to allow blocking direct sunlight as the sun tracks across the sky.
I recommend the DIY Roomba Sweeper project with Raspberry Pi. I've been toying around with this idea for a little bit and have seen a couple examples on RUclips. Some useful features would be collision avoidance and some type of space mapping algorithm.
Extremely well done comparative analysis. I would add that in addition to data collection and analysis, RPi excels at Internet-style communication, especially if you invest time in learning Python. I put custom web server front ends on most of my projects so I can use RESTful clients on my tablet and phone to control them. I also run Arduino IDE on a permanently integrated RPi zero w controller so I can update software without recabling my Arduino projects. In fact I don't even need to get off the couch.

I started with Raspberry Pi for electronics projects until I came across your channel few months ago. Since then its been all Arduino. Until you shift to Pi I am with arduino.
The raspberry pi is easier for programmers like me. Since it runs linux, there're many things to play with the software. For example, using nodejs to remotely control it via firebase is a much easier way to build complicated IOT projects.
I find RPi easier/faster to work with when whatever I'm doing has to have connectivity to networks/peripherals/etc - it's already built into the hardware. But Arduino isn't a full SBC, it's an MCU - much better when you need finer control over timings and stuff, you don't have to fight against the multitasking bloat or play within the cracks on a "full" computer - and small code runs faster, simple hardware runs faster (if it has same spec, anyhow) - MCU or SoC is just the better choice than SBC for some things.
You're not even intended to use the Arduino for really complicated IOT things. The Arduino is a microcontroller board (like @P said), you program close to the metal, you don't run a whole OS, it's better for fine control and real-time but you shouldn't use it for a web server or to otherwise communicate with networks. An SBC is far better for more advanced things, especially for things with cameras or network connectivity. There's kind of a middle ground in the form of the ESP8266 and ESP32 series, microcontrollers with a pretty good amount of processing power which are generally capable of come in boards built around network connectivity, Wi-Fi and Bluetooth, and can be easily programmed with Lua, Python or even Node.js thanks to their power and the fact that they usually have 1MB or more flash storage.
@@lithiumwyvern_ tell that to the people that make CNC controllers based on 8-bit Arduinos. :-) But yes, the different devices have different strength and weaknesses. You can still add simple network and IO protocols like for IoT. You can still use IPv6 on them, which you actually should do instead of IPv4. ;-)
As always, great video, and not for just the topic at hand (which is better for what), but the detail you go to regarding the whole process: declarations, IDE, and more. Awesome instructional and succinct! I wish more authors but as much time into preplanning executing their works. Cheers!!
7:58 What about showing us some kind of GPS tracking system for a raspberry pi, connected with the ODB2 connector of a car. ODB2 shares some info about the car's specs. Like mileage etc. The raspberry Pi could connect with the user's addressbook (contacts) or calendar via APIs to figure out if a certain trip is business or leisure.
Finally a video on the Pi GPIO - I might have a play with this soon, just for a change :) BTW, I don't understand the reason to mention 'void' all the time. Noobs keep asking the same question over and over, what this 'void' is. Just call the function Setup or Loop. No reason to mention 'void' all the time. Just my .2 cents.
Another cool way to use your Raspberry Pi, is to set it as headless, meaning no need to use peripherals. Instead you can connect to the Raspberry Pi via SSH, essentially enabling remote access to the Pi. To make your Pi headless, install the Rasbpian Lite image (no desktop available) which is very lightweight compared to full desktop version, as it doesn't install any additional software or desktop libraries. You can then connect via SSH, from your PC, to run your scripts or manage the Pi. I would recommend to use VSCode Insiders and remotely connect to your Pi to start developing. This is an IDE that provides code highlighting, as well as many other features via extensions, a really powerful, yet free tool.
I have a project where I need at least two analog outputs, X & Y and one analog input Z. Ten bit resolution in/out would be ideal. This part of the project is all hardware and will probably use a three wire SPI interface. This will be for an addressable video camera that does not continuously scan, but can operate completely statically. It can be parked on a single pixel and measure it continuously or scan in any pattern desired. Full raster, pseudo random, full random, spiral, tracking microscan, etc. Microscanning a small region also improves data collecting efficiency as the entire field of view need not be read in each time. Aspect ratio is 1:1. I want to use the Raspberry Pi because it has magnificent video display support built in and full file system support, unlike Arduino. A hybrid Pi/Arduino approach is not out of the question. For the curious, the project is called the Philocam and can be seen, in process, on my own YT channel.
i would very much like to see you control motors with the pi 3 B, i think it would be a brilliant demo of what it can do also if you need more ideas for pi videos, you could re-create some electronic analysis tool like an oscilloscope, or make a variable power supply where the pi controls the amount of current and/or voltage from variables in code. love the videos, and im glad you have started pi projects
It would be very interresting to have a video around the wireless communication (radio) between an arduino and a raspberry. Let's say the arduino is where the sensors are connected and the data logging part is on the raspberry (like that we can have a UI to display the data later)
Do the remote supervising system with motion detectors and sensors (for doors and windows). Plus the USB camera - when the sensors are triggered, than a camera can activate to start capturing (making photos) and upload them to remote account + send an alarm email/sms to you. This would combine the arduino elements (sensors) and raspberry functions (USB, access to FTP, emails, etc.). But this will be probably a project for 2 or 3 episodes.
RBPL1 I have already created one using python. It captures pics videos timelapse and automatically uploads to my Google drive (+ I have FTP and Dropbox also ) with a click of a button from a custom android app that I have built using app inventor....I am also developing the app using native android studio using kotlin. If u are really interested I can start video tutorial series.😄
I would love to see more Raspberry Pi videos. Anything would be great using Python. I'm starting to focus a little more on the Pi because it just seems more powerful and can do more complex tasks. Also, I'm trying to attempt to focus on a system since it's hard for me to learn all things things right now. Finally, I'm finding Python very helpful for my other programing tasks so learning that language is very helpful 👍👍👍
So what I wanna know is "How stable is Raspberry Pi, When it comes to inputing and outputing data on the fly?" AvE says you cannot trust arduino to not crash during critical operations that require external coms. Ex. Let's say you have a moving object that is reporting it's position to the R.P. then the R.P. does the math and tells the object to proceed to the next coordinate. The moving object is logging data. It doesn't have to transmit all the data. It just has to get 'home' safely. Can Raspberry Pi find it's way home without crashing in the woods somewhere? This may be bit long winded, but basically how stable is Raspberry Pi with processing external data?
Now I have a behavior of not putting it after programming in Kotlin, F#, TypeScript, Haskell, Python, OCaml When I program in C, for minutes I get compile errors until I switch my behavior and start putting ";", such a shame those old languages have stupid parsers hand-crafted that don't use formal parsing theory and need to be told then statements finish.
+Lulz Felipe, That is BECAUSE they are OLD languages. C is from beginning of 1970:th, made to compile Unix and the tools. The compiler theories have developed MUCH since the Algol languages (which inspired C and other languages, as they used compiler compiles, like Yacc and Lex). The computers was so slow, that the programming languages wasn't suitable for modern functional languages, and the compiler theories wasn't developed enough for languages like Haskell and Ocaml.
You can install Processing 3, this program have the hardware io library and by the way you can make a graphic environment or use a camera to control the raspberry
Thank you! I have a version 1 Raspberry Pi that I bought with big plans and never got around to doing anything with it. A CarPuter to use a touchscreen, GPS, MP3 player and interact with my Megajolt car ignition system. As an arduino. It is ovrrkill. but if you have a project where heavy processing is needed. Then yes. a RPi is the way to go.
I have an off-brand SBC with a TFT display. I used the image the manufacturer provided since I failed to deploy the kernel module myself. There are 3 GPIO pins dedicated for buttons that was not programmed. I pulled together my limited knowledge in python and managed to make the buttons send commands to i3-msg
Good video. I'm using esp32 with micropython and I truly need more processing power since my project is of a large scale and processes a lot of data. Should I get the pi 4? I mean the core speed alone is something to consider!
For us, coming from VB, XOJO allows you tu program in a fully graphic environment as well as,in a command line one, and even web. Not free, but excellent.
Great video! What is going on with the diy jbc soldering station? Are you still using it? If you don’t, what are you using as your main soldering station at this moment
One important thing, you didn't mentioned is, that you can run multiple programms in parallel, because you execute the code on a Operation system. May it's not an RTOS but in most cases it isn't necessary. I jused this fact, to controll a IR-LED in a sub-programm with delays, that didn't affect the main Programm noticeable.
Awesome! This the first C programming tutorial I've seen on the PI and it was a great introduction. A question though - can you see any advantages to using C except familiarity? I can understand that in a memory and processor limited cpu like the arduino it's absolutely needed but on the resource rich environment of the PI I think the python tooling is so much richer. Either way thanks for the video - it's great to see your detailed analysis.
It's very useful if you need performance (for example generating a pwm signal) since it bottlenecks the RPi a bit. For most applications, however, python is fine
Alan Ramírez Herrera In that way you are absolutely right. But you have to look in another way onto a Project with a Raspberry Pi. Performance is secondary.
so the raspberry pi can use something similar to timers, im not sure how familiar you are with linux, but linux can send a signal to your program, and you can then send a signal to the linux kernel, for say a timer, and then you would be able to handle timed events, and with quite a bit of work you can even make bare metal code for the raspberry pi and handle interrupts, though unfortunately this is annoying to do, because the lower level parts of the raspberry pi are quite poorly documented (you need to know hardware addresses, you have to know exactly how the pi boots up, and you have to know how to handle different cpu modes).
One of the advantages is the ability to run any linux program including webservers, etc. and still having the ability to connect your electronic parts to it.
Also the raspberry Pi (Rpi) can have connection with arduino by USB, and have a bidirectional communication, with that you can easily use both and now you have the vintages of arduino like ADC. A good project could be an intelligent cae that map his specific route and of course add another's items like distance measure, lights and so.. Interesting introduction of RPI
Connecting Arduino to raspberry pi through i2c communication will be a nice project. Raspberry pi as master and Arduino as slave. And I think this will also increase the gpio pins...
About those compiled executables you created, can you run those directly, eg immediately on powerup? Or would you have to load to OS and then boot the executable? In otherwords, will those the excutables relie on library calls to OS.
It's also possible to program the Pi directly through the PC (just for Win 10). Just install Windows 10 IOT on the PI and Visual Studio on the PC. Then open an Arduino-Wireing-Project in Visual Studio and there you go .... The thing ist, the Pi might have an other drawback besides the ones you mentioned: It can't do very accurate timing, because there is still an OS Running in the background.
I am worried about it not being able to be event timed based system. The point is arduino and pi needs to be combined mainly use pi for alexa and computer vision while arduino is for servo, pca 9685, and the accelerometers and other sensors and arduino handles machine learning or pi not sure which is best maybe arduino for machine learning since pi can't handle event based programs.
I'd like see a video on building a ceep NAS. Meaby from an old laptop or from a Pi. There are some videos of this kind here on RUclips but I really like YOUR way of explaining things. Thanks for all the hard work you put in you videos.
@GreatScott Hi, could u reuse a broken tablet? Let's say that it is completly dead with no reasons, but the screen is still fully functionable. Could u show how to reuse this screen, without loosing the touch function? Or more genereally asked, how can I reuse a touchscreen as second monitor for a laptop for example and taking the touch as a mouse. Hope you will read this question :D
Great! Exactly what I was looking for! Question: I want to use a HDMI touch screen and JS webserver so I have a GUI to interact with my GPIO pins. Any comments on doing that, please?
I have a doubt..was the led pin 15 numbered according to wiringPi numbering or BCM numbering from 8:14. From the video..I am thinking it was physical pin 10
I think that they are not comparable as they offer really different functions. For example raspberry can multitask. Arduino is a real time system... its just why can they both coexist at the same time. Because you need both of them for different things.
I have been using a pi as a controller for a robot and I have been getting very good results , The only downside is that I need to run a motor controler off a seperate 12v battery for propulsion.
Raspberry Pi = small computer. useful for - low power Server applications (like a webserver, print server, server to controll some smart home stuff etc.) - Media applications (the graphics are quite good for such a small/cheap unit) Arduino, Teensy = Microcontroller stuck on a tiny PCB. - Replaces a Microcontroller if you are to lazy to solder one into your circuit (+ it is a LOT easier to program than for something like an AVR or a PIC without a firmware/toolkit like arduino) -Useful as an usb interface / controller, like for example in homemade input devices (keyboards, joysticks etc.) and in robotics
You can always go with more powefull uCs like ARM, and other for more complex projects, pies aren't really cheap ( and not sure if worth or precise enough, you still need to run a OS in background)

Hey guys, currently I am in my internship semester and have to build a soccer playing robot. Therefore I am using an Arduino Mega 2560. It doesnt need to get a professional soccer robot. It only has to detect the ball and shoot it. Is that possible with my arduino ?
Considering a Pi 4. Dabbled with Pi3 controlling an SPI 24b ADC, but found out SPI clock was locked to CPU clock which changes with CPU temp. Unacceptable for embedded. Does the 4 fix this issue?
A few years ago, a friend of mine and I wanted to build a ECU with fuel injection and electronic ignition for an older carbureted engine with points ignition. I was thinking of using a PI or adruino. I'm not that clued up on arduino nor PI, but my friend, who knows a bit more that I do explained that the PI is much slower compared to the arduino for the purpose. Not sure how accurate this is. Would love to know your thoughts?
Half accurate. The Pi is actually a lot faster in terms of raw processing speed, but it's not built for real-time operation. The full OS it runs is always doing a hundred different things, and sometimes it might be busy for a few milliseconds at a critical moment, so you can't use it for something that needs highly precise timing control like an engine - at least not without a more appropriate operating system. The arduino is much slower, but it's also a bare metal environment - no operating system or competing applications to get in your way, so it can actually react in a much shorter time than the Pi.
I really don't think you made a big enough deal of the start up times. Microcontrollers start in next to no time, but the Pi has to load the OS. I think "adding" processing power to microcontrollers by way of sending data to a server is better than taking the power to the device. That's my two pence.
I have a couple of original Pi 1s doing basically arduino type stuff in my home automation system, but they run a basic java server. They run i2c library and I expand to a bunch of ADC inputs, and a bunch of opto isolated outputs. Why Pi, because I had them, and I wanted to have a bit more processing capability for the data. Now I'd use an esp32 for similar application, but these Pis have been in service for close to 8 years and have up times since the last time I was messing around with power -- about 250 days. The java server can do things a bit easier for data processing and analysis before sending it along to the home automation brain. For instance I can pick which ADC post processes I want to use when subscribing to an ADC input in the home automation brain, either straight data, or one of several mathematical smoothing algorithms -- SMA, WMA, and Bezier -- just the ones I implemented. Arduino could do it, but it would be pretty taxing on the CPU to that much data smoothing. Just depends what the use case is, and what you have around.
Thank you for sharing your knowledge. Great tutorial. As a feedback to your channel, I would like to see a project of a DRM/DRM+ radio transmitter and receiver, using Arduino and Raspberry Pi (which I believe could be the best choose because of the SDR processing power needed). This could be a very important development.
Thanks. I see them as complimentary systems. One raspberry pi can be connected to several Arduinos. Arduinos are much more robust if you want embedded systems though (And cheaper!)

What I'd love to see is something like a Raspberry Pi controlled system, (perhaps wit ha LCD/touchscreen interface) controlling various arduino-based sub-systems for home automation. Basically, have a PI with touch screen on the wall and connect via wifi or similar to various arduino boxes to control lights, shutters, A/C, etc.
Hi GreatScott (congrats on your interesting movies! :) ). That is to say, I need an advice ... , and so I have a question. I have to create a network based on arduino devices. One hub and 8 nodes. Hub based on arduino due, nodes are using arduino mega. You may consider this to be a sort of security system with bi-directional communication between hub and nodes. Range of communication is maximum 10-15meters. However, each arduino (9 together) must have a tft shield display on (it takes a lot of connections). What solution/device should I use to support wireless communication within this network? To note, data transmission will be very, very low. Thank you in advance. Maybe there are a few options available?
Is there a way to create a raspberry pi oscilloscope? I know that it could be quite compromising just like the oscilloscope kit you made but it would be a neat idea
I would want to use rasberry input to show a picture in screen, is that possible for me? Im amateur at rasberry things. Im trying to get "if button is pressed, show picture"
The main problem of Linux boards like RPi 3 is the fact that the interrupts cannot be handled from user space (aka your program code). Any callbacks in WiringPi are in fact polling the state of the pin and then calling when there is change of state. This is quite problematic if you want to handle lots of inputs and want to relay on precision. The other issue is the unpredictable behavior of the multi-threading code which is neat if you need them, but can be problematic if you want to drive step motors, reading speed counters or measure sonar time etc. In my projects MCU is just necessary to delegate such delicate tasks reliably.
I want to see a smart home controlling future with raspberry pi 3 which will have automatic water tank filling, power management with solar pcu. automatic stair lighting, motion sensing outdoor lighting with motion capturing, home security when in home or out of home, disconnecting the external cunnections when lightning or thunderstorm is happening to prevent internal home appliance getting damaged from lightning etc.

There's kind of a middle ground in the form of the ESP8266 and ESP32 series, microcontrollers with a pretty good amount of processing power which are generally capable of come in boards built around network connectivity, Wi-Fi and Bluetooth, and can be easily programmed with Lua, Python or even Node.js thanks to their power and the fact that they usually have 1MB or more flash storage.
@@lithiumwyvern_ tell that to the people that make CNC controllers based on 8-bit Arduinos. :-)
But yes, the different devices have different strength and weaknesses. You can still add simple network and IO protocols like for IoT. You can still use IPv6 on them, which you actually should do instead of IPv4. ;-)
As always, great video, and not for just the topic at hand (which is better for what), but the detail you go to regarding the whole process: declarations, IDE, and more. Awesome instructional and succinct! I wish more authors but as much time into preplanning executing their works. Cheers!!

What about showing us some kind of GPS tracking system for a raspberry pi, connected with the ODB2 connector of a car.
ODB2 shares some info about the car's specs. Like mileage etc.
The raspberry Pi could connect with the user's addressbook (contacts) or calendar via APIs to figure out if a certain trip is business or leisure.
Finally a video on the Pi GPIO - I might have a play with this soon, just for a change :) BTW, I don't understand the reason to mention 'void' all the time. Noobs keep asking the same question over and over, what this 'void' is. Just call the function Setup or Loop. No reason to mention 'void' all the time. Just my .2 cents.
Another cool way to use your Raspberry Pi, is to set it as headless, meaning no need to use peripherals. Instead you can connect to the Raspberry Pi via SSH, essentially enabling remote access to the Pi. To make your Pi headless, install the Rasbpian Lite image (no desktop available) which is very lightweight compared to full desktop version, as it doesn't install any additional software or desktop libraries. You can then connect via SSH, from your PC, to run your scripts or manage the Pi. I would recommend to use VSCode Insiders and remotely connect to your Pi to start developing. This is an IDE that provides code highlighting, as well as many other features via extensions, a really powerful, yet free tool.
I have a project where I need at least two analog outputs, X & Y and one analog input Z. Ten bit resolution in/out would be ideal. This part of the project is all hardware and will probably use a three wire SPI interface.
This will be for an addressable video camera that does not continuously scan, but can operate completely statically. It can be parked on a single pixel and measure it continuously or scan in any pattern desired. Full raster, pseudo random, full random, spiral, tracking microscan, etc. Microscanning a small region also improves data collecting efficiency as the entire field of view need not be read in each time. Aspect ratio is 1:1. I want to use the Raspberry Pi because it has magnificent video display support built in and full file system support, unlike Arduino. A hybrid Pi/Arduino approach is not out of the question. For the curious, the project is called the Philocam and can be seen, in process, on my own YT channel.
i would very much like to see you control motors with the pi 3 B, i think it would be a brilliant demo of what it can do
also if you need more ideas for pi videos, you could re-create some electronic analysis tool like an oscilloscope, or make a variable power supply where the pi controls the amount of current and/or voltage from variables in code.
love the videos, and im glad you have started pi projects
Nice one! I saw a lot of projects with emulator for old games on raspberryPi until ps1. But what's the real limitations? Ps2? nintendo Wii?
It would be very interresting to have a video around the wireless communication (radio) between an arduino and a raspberry.
Let's say the arduino is where the sensors are connected and the data logging part is on the raspberry (like that we can have a UI to display the data later)
Do the remote supervising system with motion detectors and sensors (for doors and windows). Plus the USB camera - when the sensors are triggered, than a camera can activate to start capturing (making photos) and upload them to remote account + send an alarm email/sms to you. This would combine the arduino elements (sensors) and raspberry functions (USB, access to FTP, emails, etc.). But this will be probably a project for 2 or 3 episodes.
RBPL1 I have already created one using python.
It captures pics videos timelapse and automatically uploads to my Google drive (+ I have FTP and Dropbox also ) with a click of a button from a custom android app that I have built using app inventor....I am also developing the app using native android studio using kotlin.
If u are really interested I can start video tutorial series.😄
Alarms in the form of SMS is also there.
Camera can act as a motion detector and sensor using opencv.
Gunesh Shanbhag are you a RUclipsrs tooo
Make video on it pls
I would love to see more Raspberry Pi videos. Anything would be great using Python. I'm starting to focus a little more on the Pi because it just seems more powerful and can do more complex tasks. Also, I'm trying to attempt to focus on a system since it's hard for me to learn all things things right now. Finally, I'm finding Python very helpful for my other programing tasks so learning that language is very helpful 👍👍👍
Hi! Can you review the raspberry Pi pico, the latest model of raspberry Pi in a much small package...
So what I wanna know is "How stable is Raspberry Pi, When it comes to inputing and outputing data on the fly?" AvE says you cannot trust arduino to not crash during critical operations that require external coms. Ex. Let's say you have a moving object that is reporting it's position to the R.P. then the R.P. does the math and tells the object to proceed to the next coordinate. The moving object is logging data. It doesn't have to transmit all the data. It just has to get 'home' safely. Can Raspberry Pi find it's way home without crashing in the woods somewhere? This may be bit long winded, but basically how stable is Raspberry Pi with processing external data?
Thanks for a great episode! I'd like to see a project with Raspberry Pi and an Arduino in conjunction, communicating with each other over I2C.
7:00 ... hahaha all the semicolons
Kinda understandable if he comes from c. Took me a month and a linter to get rid of that behavior^^
ah no shit, i just pointed it out no reason to be triggered
Now I have a behavior of not putting it after programming in Kotlin, F#, TypeScript, Haskell, Python, OCaml
When I program in C, for minutes I get compile errors until I switch my behavior and start putting ";", such a shame those old languages have stupid parsers hand-crafted that don't use formal parsing theory and need to be told then statements finish.
+Lulz Felipe, That is BECAUSE they are OLD languages. C is from beginning of 1970:th, made to compile Unix and the tools. The compiler theories have developed MUCH since the Algol languages (which inspired C and other languages, as they used compiler compiles, like Yacc and Lex). The computers was so slow, that the programming languages wasn't suitable for modern functional languages, and the compiler theories wasn't developed enough for languages like Haskell and Ocaml.
likewise we python devs forget semicolons and curly brackets when we have to code C ;)
You can install Processing 3, this program have the hardware io library and by the way you can make a graphic environment or use a camera to control the raspberry
Thank you!
I have a version 1 Raspberry Pi that I bought with big plans and never got around to doing anything with it.
A CarPuter to use a touchscreen, GPS, MP3 player and interact with my Megajolt car ignition system.
As an arduino. It is ovrrkill.
but if you have a project where heavy processing is needed.
Then yes.
a RPi is the way to go.
Thanks for the video!! I haven't really tried to use the Raspberry Pi for electronics, but seeing how it works, I think I might!
Sorry for the date but raspberry pi 3 has a 5v pin outputs. I recommend you looking for a pin schematic ;)
I have an off-brand SBC with a TFT display. I used the image the manufacturer provided since I failed to deploy the kernel module myself. There are 3 GPIO pins dedicated for buttons that was not programmed.
I pulled together my limited knowledge in python and managed to make the buttons send commands to i3-msg
Good video.
I'm using esp32 with micropython and I truly need more processing power since my project is of a large scale and processes a lot of data.
Should I get the pi 4?
I mean the core speed alone is something to consider!
For us, coming from VB, XOJO allows you tu program in a fully graphic environment as well as,in a command line one, and even web. Not free, but excellent.
Great video! What is going on with the diy jbc soldering station? Are you still using it? If you don’t, what are you using as your main soldering station at this moment
One important thing, you didn't mentioned is, that you can run multiple programms in parallel, because you execute the code on a Operation system. May it's not an RTOS but in most cases it isn't necessary. I jused this fact, to controll a IR-LED in a sub-programm with delays, that didn't affect the main Programm noticeable.
Awesome! This the first C programming tutorial I've seen on the PI and it was a great introduction. A question though - can you see any advantages to using C except familiarity? I can understand that in a memory and processor limited cpu like the arduino it's absolutely needed but on the resource rich environment of the PI I think the python tooling is so much richer. Either way thanks for the video - it's great to see your detailed analysis.
northshorepx Using Python is always the better choice on a Raspberry Pi.
It depends on the type of project.
Usually C is much faster than python because C compiles to machine code and python needs an interpreter, however, you have Cython
It's very useful if you need performance (for example generating a pwm signal) since it bottlenecks the RPi a bit.
For most applications, however, python is fine
Alan Ramírez Herrera In that way you are absolutely right. But you have to look in another way onto a Project with a Raspberry Pi. Performance is secondary.
I love you Scott, i was looking for these answers, you told them very clearly.
so the raspberry pi can use something similar to timers, im not sure how familiar you are with linux, but linux can send a signal to your program, and you can then send a signal to the linux kernel, for say a timer, and then you would be able to handle timed events, and with quite a bit of work you can even make bare metal code for the raspberry pi and handle interrupts, though unfortunately this is annoying to do, because the lower level parts of the raspberry pi are quite poorly documented (you need to know hardware addresses, you have to know exactly how the pi boots up, and you have to know how to handle different cpu modes).
Wow - *Best video* I've seen this year. Thank you for this.
It will be awesome if you can make a video on LIDAR and Maping of Unknown Environment.
One of the advantages is the ability to run any linux program including webservers, etc. and still having the ability to connect your electronic parts to it.
Also the raspberry Pi (Rpi) can have connection with arduino by USB, and have a bidirectional communication, with that you can easily use both and now you have the vintages of arduino like ADC. A good project could be an intelligent cae that map his specific route and of course add another's items like distance measure, lights and so.. Interesting introduction of RPI
Connecting Arduino to raspberry pi through i2c communication will be a nice project. Raspberry pi as master and Arduino as slave. And I think this will also increase the gpio pins...
All of your videos are highly informative.
About those compiled executables you created, can you run those directly, eg immediately on powerup? Or would you have to load to OS and then boot the executable? In otherwords, will those the excutables relie on library calls to OS.
7:04 I see what you did there with deleting all the semicolons!
He is prob used to C language and he made a mistake
It's also possible to program the Pi directly through the PC (just for Win 10). Just install Windows 10 IOT on the PI and Visual Studio on the PC. Then open an Arduino-Wireing-Project in Visual Studio and there you go ....
The thing ist, the Pi might have an other drawback besides the ones you mentioned: It can't do very accurate timing, because there is still an OS Running in the background.
I am worried about it not being able to be event timed based system. The point is arduino and pi needs to be combined mainly use pi for alexa and computer vision while arduino is for servo, pca 9685, and the accelerometers and other sensors and arduino handles machine learning or pi not sure which is best maybe arduino for machine learning since pi can't handle event based programs.
I'd like see a video on building a ceep NAS. Meaby from an old laptop or from a Pi. There are some videos of this kind here on RUclips but I really like YOUR way of explaining things. Thanks for all the hard work you put in you videos.
@GreatScott Hi, could u reuse a broken tablet? Let's say that it is completly dead with no reasons, but the screen is still fully functionable. Could u show how to reuse this screen, without loosing the touch function?
Or more genereally asked, how can I reuse a touchscreen as second monitor for a laptop for example and taking the touch as a mouse.
Hope you will read this question :D
Great! Exactly what I was looking for!
Question: I want to use a HDMI touch screen and JS webserver so I have a GUI to interact with my GPIO pins. Any comments on doing that, please?
What do you study in University to do this ? I'm a computer science major but I love coding and electronics!
I have a doubt..was the led pin 15 numbered according to wiringPi numbering or BCM numbering from 8:14. From the video..I am thinking it was physical pin 10
I think that they are not comparable as they offer really different functions. For example raspberry can multitask. Arduino is a real time system... its just why can they both coexist at the same time. Because you need both of them for different things.
4:02 void loop(){} is while(1){}
5:08 The programable GPIO pin is 3.3 V instead of 5V. Those pin which you do e.g. digitalWrite(pin, value); to!
I have been using a pi as a controller for a robot and I have been getting very good results , The only downside is that I need to run a motor controler off a seperate 12v battery for propulsion.
Raspberry Pi = small computer. useful for
- low power Server applications (like a webserver, print server, server to controll some smart home stuff etc.)
- Media applications (the graphics are quite good for such a small/cheap unit)
Arduino, Teensy = Microcontroller stuck on a tiny PCB.
- Replaces a Microcontroller if you are to lazy to solder one into your circuit (+ it is a LOT easier to program than for something like an AVR or a PIC without a firmware/toolkit like arduino)
-Useful as an usb interface / controller, like for example in homemade input devices (keyboards, joysticks etc.) and in robotics
You can always go with more powefull uCs like ARM, and other for more complex projects, pies aren't really cheap ( and not sure if worth or precise enough, you still need to run a OS in background)

Hey guys, currently I am in my internship semester and have to build a soccer playing robot. Therefore I am using an Arduino Mega 2560. It doesnt need to get a professional soccer robot. It only has to detect the ball and shoot it. Is that possible with my arduino ?
Can you try making super capacitors and check if making them is an alternative to buying expensive battery packs
Hey scott what about a review of a cheap power supply for those of us that are unsure about wiring up an AC power supply ourselves?
Considering a Pi 4. Dabbled with Pi3 controlling an SPI 24b ADC, but found out SPI clock was locked to CPU clock which changes with CPU temp. Unacceptable for embedded. Does the 4 fix this issue?
A few years ago, a friend of mine and I wanted to build a ECU with fuel injection and electronic ignition for an older carbureted engine with points ignition. I was thinking of using a PI or adruino. I'm not that clued up on arduino nor PI, but my friend, who knows a bit more that I do explained that the PI is much slower compared to the arduino for the purpose. Not sure how accurate this is. Would love to know your thoughts?
Half accurate. The Pi is actually a lot faster in terms of raw processing speed, but it's not built for real-time operation. The full OS it runs is always doing a hundred different things, and sometimes it might be busy for a few milliseconds at a critical moment, so you can't use it for something that needs highly precise timing control like an engine - at least not without a more appropriate operating system. The arduino is much slower, but it's also a bare metal environment - no operating system or competing applications to get in your way, so it can actually react in a much shorter time than the Pi.
I really love your videos. I like how you write down things too.
I really don't think you made a big enough deal of the start up times. Microcontrollers start in next to no time, but the Pi has to load the OS. I think "adding" processing power to microcontrollers by way of sending data to a server is better than taking the power to the device. That's my two pence.
I have a couple of original Pi 1s doing basically arduino type stuff in my home automation system, but they run a basic java server. They run i2c library and I expand to a bunch of ADC inputs, and a bunch of opto isolated outputs. Why Pi, because I had them, and I wanted to have a bit more processing capability for the data. Now I'd use an esp32 for similar application, but these Pis have been in service for close to 8 years and have up times since the last time I was messing around with power -- about 250 days. The java server can do things a bit easier for data processing and analysis before sending it along to the home automation brain. For instance I can pick which ADC post processes I want to use when subscribing to an ADC input in the home automation brain, either straight data, or one of several mathematical smoothing algorithms -- SMA, WMA, and Bezier -- just the ones I implemented. Arduino could do it, but it would be pretty taxing on the CPU to that much data smoothing. Just depends what the use case is, and what you have around.
I would like to see how to do computer vision (like YOLO object detection) on a rasperry pi board. Wish you the best, Great Scott!
You can also install node.js on the pi and use javascript to program it, which solves the problem of timers as javascript is event based
Do you feel at all limited by the amount of various types of pins. Analog pins for example.
Can you make a video on soldering station vs the soldering rods ie. 60w and 90w....which are even digital....so which one to buy.....
Thank you for sharing your knowledge. Great tutorial. As a feedback to your channel, I would like to see a project of a DRM/DRM+ radio transmitter and receiver, using Arduino and Raspberry Pi (which I believe could be the best choose because of the SDR processing power needed). This could be a very important development.
Thanks. I see them as complimentary systems. One raspberry pi can be connected to several Arduinos. Arduinos are much more robust if you want embedded systems though (And cheaper!)
Fun fact:In future you can officialy run Arduino Schetches on rPi ": The idea is there's a tonne of people that know how to use Arduino and they can take their knowledge and apply it to this," Banzi told the Embedded Linux Conference 2018 in Portland in the US.
Hi Dear, There is library to control SSD1306 in nodejs javascript for rasberryPI4? or need to convert the c library from arduino to raspberry PI? Best Regards Youssef
Do a zero-cross voltage level proyect or something that controls the power output but with an micro Controller! Would love that (maybe even a PID)
Please someone answer,
Why do you use raspberry pi as Arduino, why not simply buy Arduino that is cheaper also?
I really do not know that what really is the use of raspberry pi if you have smartphone, good PC/Laptop and Arduino beforehand? (Please tell and share some of your knowledge with me because I am new here)
Thanks
Does this work on Raspberry Pi "compatible" boards, for example, the Orange Pi PC?
Always enjoy your videos.
how big of an lcd can i control with an arduino i would like to make basically a program to aid with my other hobby of farming using things like gps to help keep a even spread during broadcast seeding and another use would be during plowing to monitor plow depth with possibly ultrasonic sensors or is this to complicated for an arduino would a raspberry pi be better suited for the tasks at hand
Are there enough digital pins to make a 3D printer from the RPi?
Great Scott please make a video on *What is tinker and how to use it*
What I'd love to see is something like a Raspberry Pi controlled system, (perhaps wit ha LCD/touchscreen interface) controlling various arduino-based sub-systems for home automation. Basically, have a PI with touch screen on the wall and connect via wifi or similar to various arduino boxes to control lights, shutters, A/C, etc.
Raspberry Pi also has a 5V GPIO pin, just clearing that up! Great video
I had been always waiting for this video super helpful video
Hi GreatScott (congrats on your interesting movies! :) ). That is to say, I need an advice ... , and so I have a question. I have to create a network based on arduino devices. One hub and 8 nodes. Hub based on arduino due, nodes are using arduino mega. You may consider this to be a sort of security system with bi-directional communication between hub and nodes. Range of communication is maximum 10-15meters. However, each arduino (9 together) must have a tft shield display on (it takes a lot of connections). What solution/device should I use to support wireless communication within this network? To note, data transmission will be very, very low. Thank you in advance. Maybe there are a few options available?
Is there a way to create a raspberry pi oscilloscope? I know that it could be quite compromising just like the oscilloscope kit you made but it would be a neat idea
Hello. I burned my RP3 with overloading 19V. Now it doesn't work.Any idea or help?
I would want to use rasberry input to show a picture in screen, is that possible for me? Im amateur at rasberry things. Im trying to get "if button is pressed, show picture"
The main problem of Linux boards like RPi 3 is the fact that the interrupts cannot be handled from user space (aka your program code). Any callbacks in WiringPi are in fact polling the state of the pin and then calling when there is change of state. This is quite problematic if you want to handle lots of inputs and want to relay on precision. The other issue is the unpredictable behavior of the multi-threading code which is neat if you need them, but can be problematic if you want to drive step motors, reading speed counters or measure sonar time etc. In my projects MCU is just necessary to delegate such delicate tasks reliably.
I want to see a smart home controlling future with raspberry pi 3 which will have automatic water tank filling, power management with solar pcu. automatic stair lighting, motion sensing outdoor lighting with motion capturing, home security when in home or out of home, disconnecting the external cunnections when lightning or thunderstorm is happening to prevent internal home appliance getting damaged from lightning etc.
Awesome, dude! That's a great option for more complex projects! 😊
