Great video! Just a small comment - It doesn’t matter where you put the resistor. It can be either on negative or positive side of the LED. It will still limit the current that goes through.
Great instructional video! I've watch many videos on very similar functions, but the way you explain each function, while showing the dual view (well, tri-view), made each step easy to follow. You've taken the fear out of programming. Thank you and keep it up!
Setting up a circuit to add to outdoor motion lights when one catches motion, it turns them all on. This was a perfect tutorial to get the basics I needed of using GPIO to detect input. Thanks.
This was brilliant E-Man, thank you. Looking forward to much more raspberry pi videos especially when coding using Python and the RPi's GPIO pins. I simply love tinkering with these SBC.
This was super useful as someone that knows how to program + a little circuit knowledge. If you do more like this, hooking up a motor to a similar event would be cool.
You just gave me one more reason to start learning Python. Especially since I already have two Raspberry PIs that I switch back and forth between different projects (mainly retro gaming, music and video streaming).
Really nice video, Questions, I'd like to connect to Pi & run python remotely, what kind of editor you recommend for Python (Windows app?)? I saw you mounted some drive or network drive, can you explain what working environment you have?
How would I simulate a button press from another Pi? In other words, taking your example in this video, instead of having the physical button you had jumpers from another Pi. How would you define the GPIO pins in software for both Pi's? My idea is to use a WiFi enabled Pico W to trigger a button press on a 3B+ running Fruitbox (Jukebox software). I would then be able to use my phone's browser to control some aspects of it.
are the pins the holes on the pcb or is it the little metal prongs that go through the holes? Also can you solder wires to get info/energy from the holes?
One thing that I would be interested to see is actually a step further towards the "basics" and have demonstrate how to launch code on a PI. That, but also I would be super interested to see about things that you can do with a RaspberryPi that you can't do with something like an Arduino.
Since the PI has an operating system the Arduino is better for processing sensors and in general interfaceing with the environment. The PI has a bunch of stuff to do so it only gives the Arduino a piece of time to do it's thing. If you want to control something use an Arduino. Anything with an O.S. will be slow, slow, slow.
Hey, I plan to use Raspberry as a NAS using OpenMediaVault and I want it to act as a microcontroller to control some of my projects (on Arduino at this point, but my goal is to control them through PI's GPIO pins). How can I achieve both of those goals? Open Media Vault works in headless mode, no monitor and gui, everything controlled from other PC connected to the same network. Do you have any clues? Controlling GPIO in headless mode similar to microcontroller like Arduino or menaging Open Media Vault in normal Raspbian or something
Do you have a script when the button is pressed it calls not for an LED but rather a shell script/file? Is the ‘callback’ would be the call for my script.
Is it in any way possible to utilise the GPIO pins of a Raspberry Pi that is running a Home Assistant instance? IE to connect to the sensors of an old home alarm system.
Your the best, im new to this and was understanderbly clear, cheers from down under Australia, can you maybe do tutorials using all the gadgets? How to go to install programs for your shields and install things through terminal onto Raspian so many people just assume because you have a Pi your and expert, but im just making the change over and people can be so arogant i cant see why people give up and run back to windows and never look back and hate the linux community or open source community. But you were very good going step by step and explaining why each step is like it and what piece does what and why this command command does that and if if you dont sceanario. New Subscriber
Engineer Man how does that work though? A series circuit would have the same current regardless of where the resistor is. A hookup error doesn’t seem to change the circuit topology.
How would you convert an audio file into dsd to be played back through the PWM methods in this video? PDM is basically the same as PWM but instead of modulating the pulsewidth via time, it’s by keeping it on or off over clock cycles at a really high clock speed. All you would need is a capacitor to filter the high end. Would it be possible to use all the GPIO pins to output this kind of signal?
Good and complete video about RP GPIO manage, hope you may make a video using RP with hardware interrupts like we can make with microprocessors (INT), thanks!
Great video! I would like to see more RPi projects. This was a great warm-up to show how simple and powerful an RPi can be with just a little coding experience. I always thought a gun RPi project would be modifying an old garage door opener to a "smart" garage for opener with a RPi Zero. What do you think?
Cool vid! Quick question. Could you use a variable, like the led_on variable, to set the GPIO state instead of GPIO.HIGH/LOW? This would eliminate the need for the if..else statement in the switch function (I could test this myself, but others might be interested).
I am in need of some coding help, I want time.sleeep(X) and I need X to be taken from another file. I am then going to have that file IE: input.txt have its values inside change from a php script\website. no one has been able to tell me how to do this.
I would like to correct you at 830 approx. you state that GPIO23 has no value or arbitrary value, BUT in the industry we refer to these open pins as floating.

Loving your from-the-ground-up approach: great for learning how actually to build on the Pi. Hope you’ll make this a series.
Great video! Just a small comment - It doesn’t matter where you put the resistor. It can be either on negative or positive side of the LED. It will still limit the current that goes through.
Definitely more RP videos! Or even some basic electronics could be interesting :)
This is the first video I’ve seen of yours but it’s certainly not the last. Everything explained thorough but succinctly without any waffle.
Glad it helped :)

Thanks!
Most clear coding example I've seen for the RPi. Definitely more RPi videos please I recently fell into the RPi rabbit hole.
Eyyy loved the video. Please continue and make this a series
Excellent hello world here. I’ve done Pic and Arduino now for decades, just got a Pi, just needed this to figure out where to start.
I was going to do a RPi project this summer that involves 7-segment displays. These are really helpful, hope you do more.
Setting up a circuit to add to outdoor motion lights when one catches motion, it turns them all on. This was a perfect tutorial to get the basics I needed of using GPIO to detect input. Thanks.
This was brilliant E-Man, thank you. Looking forward to much more raspberry pi videos especially when coding using Python and the RPi's GPIO pins. I simply love tinkering with these SBC.
Awesome video. I'd love to see more Arduino and Raspberry Pi projects in the future.
agreed
Nooooo, look for that in another channel, don't transform this in more of the same shit
This was super useful as someone that knows how to program + a little circuit knowledge. If you do more like this, hooking up a motor to a similar event would be cool.
You just gave me one more reason to start learning Python. Especially since I already have two Raspberry PIs that I switch back and forth between different projects (mainly retro gaming, music and video streaming).
Thank you, always love videos about Raspberries
R Pi uses round the house would be a good vid
Keep them coming! Worked with Pic Micro and Arduino but just getting into Pi. Where did you write the code and where did you execute it?

That's a great tutorial, thank you. Please make more on this exact topic and more advanced physical projects. Thanks!
Super new to raspberry and arduino. Which IDE are you using?
Do you have a script when the button is pressed it calls not for an LED but rather a shell script/file? Is the ‘callback’ would be the call for my script.
First time I've seen (what seems obvious) the use of an ide cable with a pi... Nice! And Clean!
Would love you to continue this series for sure my man!
Is it in any way possible to utilise the GPIO pins of a Raspberry Pi that is running a Home Assistant instance? IE to connect to the sensors of an old home alarm system.
Only recently started with a RaspberryPi Zero, so would love to see more videos.
Whats up man, I like this raspberry video, thank you so much!
Great video, I learned a lot thanks to you. I love the RPi and look forward to seeing the next videos you make about it. Cheers
hope that this becomes a series! keep up the great work...
What if it's not blinking? I can't measure voltage at the GPIO.
How are called this pins? I want to buy on ebay, i need it exactly this what are, the basic M/M pins?

I do not believe it matters which side you put the resistor on a LED
Taylor Hardin it doesnt.
It does, for security reasons :v
Josue Rodriguez no it doesnt. prove otherwise.
You're both right, it doesn't. The selection of that side was to guarantee lower current in the event of a mistake hooking it up,
Engineer Man how does that work though? A series circuit would have the same current regardless of where the resistor is. A hookup error doesn’t seem to change the circuit topology.

I always thought a gun RPi project would be modifying an old garage door opener to a "smart" garage for opener with a RPi Zero.
What do you think?
Does the resistor have to be on the positive side coming in?
I’m yet to find a decent button which one did you use
Do an apdated version of this.
Cool vid! Quick question. Could you use a variable, like the led_on variable, to set the GPIO state instead of GPIO.HIGH/LOW? This would eliminate the need for the if..else statement in the switch function (I could test this myself, but others might be interested).
What program are you using to do this for the raspberry pi?
I like your videos before watching them
Are the GPIOs same for raspberry pi 3 and 4?
Thank You, I'm trying to learn this!
You're running this as the root user - is there a way to get this running as a 'normal' user without sudo?
Can you do some on OS Raspberry Pi cluster moving ICE is simple and easy cluster and thank you
I have a 15 nodes RaspberryPi Cluster for virtualization
i subscribe because this channel can teach me on raspberry pi as what it was.
More raspberry pie stuff would be awesome to see!
Perfect tutorial to get started with gpio!! Thanks
Clarified the BCM and Board setting...had me for a day trying to figure if the outputs were set right in the program..
Random pixelization at the top side of your PiJuice makes it appear to letting out the magic smoke.
Very helpful video - I'd like to see more.
Would like more raspberry pi videos. Thanks!
I'd like to see more videos like this one, too. Thank You!
Extremely helpful video
This is sweet. Especially love that the code is in python. Please make more.
hi man, i must do the same thing using forth, any tips?
Great intro - now how do I do it in C? I assume it's trivial, but could use a simple example like you've done here for python!
Look into the WiringPi or BCM2835 libraries, for extra points you can control the pins directly by using Linux kernel functions.
Super good! please more!
This video is exactly what I was looking for. Thanks.
Great video, and a raspberry pi series would be awesome!
what switch did you use ?
Thank you, very useful video!
How can you edit python remotely, what do you use?
man great video! keep it up PLEASE!
Can‘t you change the voltage of the gpio output ?
I am in need of some coding help, I want time.sleeep(X) and I need X to be taken from another file. I am then going to have that file IE: input.txt have its values inside change from a php script\website.
no one has been able to tell me how to do this.
Great intro, can you possibly do something with reading data from an input such as a temperature sensor, movement detector etc?
How to use multiplexed GPIO pins? I can't use that pin????
thanks for the videos bro, looking forward to more pi gpio tutorials
Great introduction!
Extremely helpful, I got all the information I needed, thank you so much!
I would like to correct you at 830 approx. you state that GPIO23 has no value or arbitrary value, BUT in the industry we refer to these open pins as floating.
Yes, do some more Raspberry Pi videos!
Awesome video! More please.
how about clustering raspberry using pins to connect each raspberry.
So good mate, keep the Raspberrypi vids coming I say!
How are you transferring the data to the PI is it connected to a computer
I used SSH.
Thank you! More please!
Which OS is this?
Thanks Engineering Man!
More Raspberry PI Videos please!
Great video, would love to see some python pi and sensor stuff
Superb.... Please do more raspberry pi video's
I soo Love my Raspberry Pi 4b.💙
Loved the video!
Keep showing the RPi stuff!
Great Video
thank you its really helpful
This was awesome manx
Nice explanation.keep it up
Please more pi videos!
Which IDE do you use?
Atom (atom.io).
Awesome video. This is a great channel.
Anyone got epoll to work with Buster? i use JS and seems its borked.
Yum, more Pi please 8-) Or perhaps micropython on the ESP8266
super helpful
