Good catch. I will add a note to the video. You can down load corrected pinout here: toptechboy.com/understanding-raspberry-pi-4-gpio-pinouts/pinout-corrected/ Next couple lessons unfortunately also have this error, but I will correct it in future videos. Thanks for your help!
Unfortunately, the old GPIO library has been discontinued due to hardware changes in Raspberry Pi. The new method for controlling GPIO is by using libgpiod. Here's an example to turn an LED on and off: Note: You must use BCM pin numbering, not BOARD, which is why GPIO 17 is used in the example. Cleanup is no longer necessary. import gpiod import time chip = gpiod.Chip('gpiochip0') line = chip.get_line(17) line.request(consumer='LED', type=gpiod.LINE_REQ_DIR_OUT) line.set_value(1) time.sleep(5) line.set_value(0)
Just Received my kit and started following this series. No programming background at all. (outside CNC and robotic programming). I am loving this series, and looking forward to getting all the way through it.... long way to go. I never thought i would be this happy about a blinking light lol!! Awesome! Homework is done, may jump to lesson 5 tomorrow!!
Following along with the Pi 5 has been smooth sailing up until this video, where RPi.GPIO can no longer be used unfortunately. I will try to follow using gpiod, but it seems more complicated. With that aside, tutorials have been really great so far! EDIT: I noticed the Raspberry Pi documentation recommends using "gpiozero", though it works much differently than "RPi.GPIO" using device objects rather than controlling the pins directly which I'm not a fan of. On the other hand, "gpiod" seems more complicated and above all, has very little documentation (atleast of what I could find). For anyone looking for a library like RPi.GPIO, I definitely recommend "lgpio" which behaves very similarly. The biggest difference it seems is the chip select, but this is because of Pi 5's new structure. This is very easy to use, just by selecting chip "4" (use "chip = lgpio.gpiochip_open(4)" ). Then, follow the "lgpio python" documentation to use the gpio pins by using the "chip" object as a handle. Hope this helps someone!
This is so exciting! I'm thankful you started out very simple because I know the homework is pretty basic but it still took a while for me to figure it out. I'm really excited for the rest of this series! Just turning on and off an LED with code is blowing my mind as someone who has only done basic computer coding. Somehow it feels more magical when you're actually affecting things in the real world!
Hello from South Texas! Thanks for the great lesson and video playlist! I recently got a job building weather instrumentation for a university. Most of the instrumentation is done using a Raspberry Pi, and I am just starting out. Just wanted to share my thanks and appreciation for your videos!
You are the best I am a a stem teenager and I really wanted to learn alot of things about robotics and I found all my answers in your videos. Thank you very much
Thank you so much for this. I do have some programming background but never any hardware. Seeing the LED turn on brought almost a tear to my eye as it reminded of my initial journey in programming. Thank you!!. FYI. folks with a Raspberry pi 5. this instructions wont work. RPi 5 changed some things and code written for previous pis wont work.
Something strange is occuring on my 16 channel relay board, connected to a t-cobbler. The GPIO.output, LOW and HIGH commands are inverted in polarity. I really don't understand it. But in the code I have to invert the commands to send signals. Any ideas?
I have raspberri pi 5 running Python 3.11.2 (main, Sep 14 2024, 03:00:30) [GCC 12.2.0] on linux I copied your code to blink the LED but following line gives the error, >>> GPIO.setup(11,GPIO.OUT) Traceback (most recent call last) : File "", line 1, in RuntimeError : Cannot determine SOC peripheral base address . Please help with this error
Sir in the GPIO pin out you've shown in the beginning (10:40), you've shown pin 6 as TX. However Google images shows it as Ground for Raspberry Pi 4, Model B. Is this for a different model? Thank you in advance for clarifying. 😊🙏
Hey Paul, I got the RPi 5 and a SunFounder kit but when I try to setup GPIO.OUT I get : "RuntimeError: Cannot determine SOC peripheral base address". My understanding is that the new RPi 5 has a new chip and I cannot use the GPIO library so can't follow your lessons. I have been able to interact with the LED through GPIOD however I don't believe I can follow your lessons as it's very different code lines. What is the best way to follow the lessons? would a cheap Pico be able to use the GPIO library? I can't justify buying an older RPi 4 now as gpio library has been deprecated.
@@paulmcwhorter Dear Paul, I really enjoyed your lesson so far, sadly I have the kit and pi as well and get the same error messages… it’s quite annoying tbh. As someone without experience it is difficult or impossible to follow your course. Maybe you can talk to sunfounder that they not advertise the set for raspberry pie 5 or ask them if they can pay you to run an updated version. I know this is not your fault but for me on the consumer end it is more than annoying, what I do now with this 60$ half-used set
Hi Sir, I am very thankful that you are doing this series. I am using Pi5 and at 35:00 i am getting the error as Traceback (most recent call last): File "", line 1, in RuntimeError: Cannot determine SOC peripheral base address please help me! Thanks in Advanced
I have an obsolete kit from NRI made by fishertechnic. I haven't been able to use since I can no longer run the software A fortran based language geared to the proprietary interface in the kit. Distributed on(5.25" floppies, IBM xt) I would like to use the raspberry pi instead. However this will require running some small 5v motors. I don't want to power the motors from the pi. I need a driver circuit to switch a separate supply to the motors
Thank you Mr. Paul. RuntimeError: Cannot determine SOC peripeheral base address. Could you please tell me why this error appears though I followed the steps in the video? (this occured after the GPIO.setup(11,GPIO.OUT). I am using Rasppi5. Thank you
If you type ‘pinout’ without the quotes, on the terminal you get a basic diagram of the actual model of Pi you are using, some basic information about it and a GPIO diagram. The GPIO diagram shows the board PIN numbers power and ground pins and the GPIO numbers but there is no extra information about the use of the GPIO pins i.e. UART, I2C etc
After watching this video twice, I see the advantages of library you used over the GPIO Zero library used in Official Raspberry Pi Beginner's Guide. Also, I've been using VSCode on my Pi400 without difficulty. The breadboard adapter makes for a more Arduino-like experience than attaching wires directly to the Pi.
I also wondered why Paul chose this library. After some reading I see that GPIOzero is a wrapper for RPi.GPIO and handles some of the setup code for you. Most of us are coming from Arduino and understand setup and pullup / pulldown so I think RPi.GPIO was the right choice. It is good to know about GPIOzero as you will see it in example code online.
The circuit diagram shows a 5v battery. Does the command 'GPIO.output(11,True)' set pin 11 at 5V by default? Can we set the voltage at any desired level using the output function?
Hi Paul, I'm running into an issue when I run the line "GPIO.setup(11,GPIO.OUT)" It is giving me an error saying, "RuntimeError: Cannot determine SOC peripheral base address." Do you have any ideas why? Thanks for everything so far, really enjoying your course!

Hello! Nice lesson Paul, I understood everything. 🎉But as I wrote in the command: GPIO.setup(11,GPIO.OUT) I got this: RuntimeError: No access to /dev/mem. Try running as root! I tried running the program with sudo python3 and then it worked. Is there another way to solve this problem, because I'm affraid, that if I write a wrong command I could remove the hard/software or something like that.😅
Hi paul, I just wanted to ask before i buy the kit. Is the raspberry pi included in the kit itself? Or the kit only has components without the raspberry pi. Is the raspberry pi included in the Sunfounder kit? The one you have in the video
Hi Paul In the first video for this series, someone corrected you for pronouncing the 'G' in GNOME. I wasn't sure but I was biased towards pronouncing it. Well it turns out that you were right👍(as usual). GNOME is an acronym for “GNU Network Object Model Environment,” and since the 'G' in GNU is pronounced and GNU is the first word in the GNOME acronym, the 'G' in GNOME is also pronounced.
Hi Mr.McWorter as always thanks for your great videos . unfortunately in my country with my income I cant afford to buy a raspberry pi although I am really interested and full of ideas and so passionate about it. is there any simulator or anything that I can rely on for learning raspberry pi thank you sincerly,
I don't know is this the better answer for you. Your alternative choice is to buy a Raspberry Pi Zero 2W at US$15. Not that expensive, hoping that it is more affordable.
Homework solved!!😁 I even added another user-input about the time delay between 2 blinks. So the blinking is sometimes too slow or too fast, depending upon the user-input. 😀 This is really exciting!!😃 And thank you for mentioning the amazing "time" library of Python.❤
I've learned how to do a Breadboard because of you Paul. Another RUclips teacher showed me tips to create a breadboard with cobbler. Excellent choice I even recommend it. Cobblers avoid actual Rasp Pi pinouts from getting damaged. I'm just over a year and a half from having this amazing machine It taught me much in such a very short time. Please check out my work. when you have the time... Thanks Paul.......🙂👌👍
I've been enjoying these videos, until now. I'm using a Raspberry Pi 5, which doesn't use RPi GPIO. The Pi 5 uses GPIOZero. I'm currently struggling with that! Hopefully I can jump back on these videos, once I figure out what the heck I'm doing with GPIOZERO.
I gotta laugh. It took me longer to figure out how to load this video to RUclips than writing the program (not quite). I did it mostly on my own except for the exception handling. Thank you ChatGPT. My program worked fine until I tried breaking out of the while loop with ctl-z. It never got to clean out the GPIO pins. With the exception and ctl-c it worked fine.
Great videos. Some timestamps would help greatly. If you could also keep the picture of you small rather than large so we can see the content, that would be super.
Hi Paul - thanks again for providing these materials, they are much more pleasant than reading dry tutorials! Would you be able to check my computations below? I'm trying to figure out how to select the correct resistor. According to my internet research (probably reliable but who knows): * 3.3 volts is the amounted provided by GPIO pins * 1.8 is the voltage drop for the red/green/yellow LEDs in our kit * 8 milliamps is the default max amperage on a GPIO pin * R = (VS - VD) / I, where R = Resistance, VS=voltage supplied, VD = Voltage Drop, I = current So by my calculation and research, the lowest resistor value meeting the 8 milliamp max should be: R = (3.3 - 1.8) / .008 = 187 ohm I.e., we should have at least a 187 ohm resistor to avoid sending too much current through the pin. Am I correct? Thanks in advance

Hi Paul - thanks again for providing these materials, they are much more pleasant than reading dry tutorials!
Would you be able to check my computations below? I'm trying to figure out how to select the correct resistor. According to my internet research (probably reliable but who knows):
* 3.3 volts is the amounted provided by GPIO pins
* 1.8 is the voltage drop for the red/green/yellow LEDs in our kit
* 8 milliamps is the default max amperage on a GPIO pin
* R = (VS - VD) / I, where R = Resistance, VS=voltage supplied, VD = Voltage Drop, I = current
So by my calculation and research, the lowest resistor value meeting the 8 milliamp max should be:
R = (3.3 - 1.8) / .008 = 187 ohm
I.e., we should have at least a 187 ohm resistor to avoid sending too much current through the pin. Am I correct? Thanks in advance
Voltage drop across a diode is 0.6v not 1.2v
can you help me please , I can not understand this error and how Can I solve it ??

I wish you were my Physics Teacher
How's your church plant going??
Slow, but progressing. Purchasing property is a challenge right now.
@@paulmcwhorter I see, do you need more donations?
Thank you for your kind thoughts. Actually I dont get donations or support for the work I do here. I support it from the work I do on this channel. So, supporting the channel supports the work I do here. The problem with property purchase is one of finding the right spot at the right price. Also, most property here does not have a title, and then issues of easements and other things make it a challenge. So, we continue to try and work through all those issues. Thanks for asking.
@@paulmcwhorter Ok, makes sense. I will be praying!
