How do you connect your board with sensors, controllers, other boards, and electronics, when those devices have different protocols and voltage? "For each board you use you will find a different GPIO setup" explains Vinicius. Check the Raspberry Pi cheat sheet that describes the GPIO pins for the Pi.

In this video, you will learn how to use digital ports, PWM, serial communication such as UART for the Raspberry Pi, and level converter for any boards.
