Raspberry Pi Beginner Guide (wiringPi Tutorial for Linux BASH Shell and C, GPIO LED Blink)

*****************************************
Update, March 2024:

WiringPi has been updated to support the latest Raspberry Pi 4/5, but it is not included with default Raspberry Pi OS image. You can use the following commands in your Raspberry Pi Terminal to get WiringPi installed:

cd wiringPiBasics

The above will give you access to the 'gpio' command and you will be able to compile C programs that use wiringPi library, for example:

gcc -Wall blink.c -lwiringPi -o blink
*****************************************

This tutorial shows how to get started with Raspberry Pi GPIO using the wiringPi library. You will be shown the full process starting with a simple circuit build, Linux shell commands needed all the way to a fully-functional C program which will blink LEDs. I spend considerable time explaining how to safely deactivate GPIO ports after use to avoid damaging them.

If you are just starting out with the Raspberry Pi this is the tutorial for you, even if you have not programmed in C before. However, making more advanced projects requires a deeper knowledge of C. In most cases I recommend Python, which is a lot more friendly to beginners. The gpio shell command always comes in handy.

So much substance in such a short video!!

Compilation command shown in the video may not work on latest Raspberry Pi OS. Use the following command instead:

gcc -Wall blink.c -lwiringPi

OR

gcc -Wall blink.c -lwiringPi -o blink

WiringPi V3.0.1 has just been released with support foir the RPi 5

Thanks. What's the process to download wiringPi on a PC then copy it to the Pi's microSD card to install it, instead of having the Pi online?

sadly wiringPi no longer exists. the site is dead
