Learn to use the Raspberry Pi GPIO connector and the gpiozero library to interface with an LED and some switches. We’ll even make a very simple camera and have our Pi take a selfie!

The GPIO (General Purpose Input/Output) is a 40-pin connector on every modern Raspberry Pi board that allows you to expand your Pi and connect it to external sensors, drivers and displays. And today we’ll start from scratch and see how easy it is to interface simple devices to the GPIO and control them with Python, using the gpiozero library.
When we need to interface with sensors, displays or motor drivers we generally use an Arduino, but there are several advantages to using a powerful microcomputer like a Raspberry Pi. With its increased processing power, large storage and memory and ability to interface with the Internet and Bluetooth it can add a new level of power to our projects.
The 10-dollar Raspberry Pi Zero W is a viable replacement for an Arduino board, and it's the Raspberry Pi that I’ll be using in today's demonstrations. In fact, everything I demo today could have easily been run on a 5-dollar Raspberry Pi Zero, as we don’t need the networking or Bluetooth capabilities.
We’ll keep it simple today and only interface with an LED and a couple of pushbutton switches. Just so you can get a good feel for how easy it is to code for the GPIO, thanks to the power of the gpiozero library.
To make it interesting the final demos will also use the Raspberry Pi Camera, and we’ll build a functional digital camera with only a few lines of code. Try that with an Arduino!
Here is the table of contents for this rather long video:
00:00 - Introduction
01:45 - Pi vs Arduino
06:35 - Selecting a Raspberry Pi
10:28 - GPIO Prototyping Accessories
15:41 - Raspberry Pi GPIO
19:51 - gpiozero Library
21:23 - Hooking up to the GPIO
22:51 - Setting up the Raspberry Pi
25:00 - Blink Compare (Arduino vs Pi)
33:14 - LED and Button Experiments
40:17 - Hooking up the Camera Experiment
41:20 - Controlling the Camera
While today's demos are extremely simple they will pave the way to doing more complex things with the GPIO, and I’ll be doing that in future videos. Make sure you’re subscribed to the channel so that you don’t miss those!
And keep in mind that the Raspberry Pi GPIO has been unofficially adopted by many SBC (Single Board Computer) manufacturers, so learning to interface to the Pi will also open the doors to working with several other platforms.
BTW, for those who make it through this long video, there is a short “blooper” at the end!
Enjoy the video!

That model really impresses me, because it's virtually a desktop computer replacement. All good wishes, sir!

There are many different Arduino IDE compatible microcontrollers now. I was late to the Arduino world. I got started with the BASIC Stamp and their Javelin board. I bought one genuine Arduino Uno to help support their effort. It was much slower, less capable and more expensive than other options. I’ve rarely used it. I’ve mostly been using the ESP 8266, ESP32 and ATSAMD boards. The newer Arduino boards may help them to be more competitive. Certainly the Arduino Uno is a great tool for some things, I just mostly skipped over it due to when I got into this hobby. These days I’m also getting away from the Arduino IDE, and using Platform IO. I’m open to trying the new Arduino Pro IDE when it is further along. I need project settings.

Hi! I believe there is a mistake on the slide at 3:48 A byte (B) usually means an octet [eight bits (b)] and computer memory and storage size is usually expressed in bytes instead of bits. As far as I know after searching online, the RAM and SRAM size units in the slide should have been [kB, MB, GB] instead of [kb, Mb, Gb] For example, the ATmega328 has 2 kB (16 kb) SRAM and 32 kB (256 kb) flash memory. The number etched on the top of SRAM and flash chips is usually in bits, though, and so are transfer speeds. I really like your videos, keep up the good work! :)

Thanks for video, that shows the unlimited capabilities of combine gpio with a computer, I guess it is the next steps learning after MCU is under control. Combined by displays, mqtt, cameras, HMI and so on possibilities are unlimited!! This is my first contact with Python and seems more compact language than Arduino C, interesting to keeping curious mind. Thanks again, hope to see more videos like that.

Hey ! I love your channel and your videos ! I just wanted to correct a few things, arround 4:50, you says Raspberry needs a bunch load of USB devicesto get starting. I actually find it much easier to start than arduino. I just use for my PI : USB power supply, SD card. Having the computer connected to the wifi is really easy, and using SSH to get distant access is easy to. You just need a computeur to SSH into the pi, but you don't need USB devices to access and programm it. Wich for certain case it's easier than accessing the USB port of an arduino builted in the project. Anyway, thanks a lot fort the sharing of this very good video :D

In a couple of the Python sketches, the code was in a While block. Great, and easy to relate to Arduino. But other Python examples have NO LOOP, and end with a call to pause (), with no mention of it or explanation of what it's for (except to say your pausing the program). Maybe it goes beyond your intended scope, but I really think you should've explained how the functions (objects) keep working, and don't just end! Anyone coming from an exclusively Arduino background won't have any idea of what's happening here.
