Raspberry Pi and Arduino - Go to The Next Level - Activity 05 - Set RGB LED from the Raspberry Pi when Pressing on Push

This video tutorial explains the bidirectional communication between an Arduino and a Raspberry Pi. It covers how to detect a button press on the Arduino, send a message to the Raspberry Pi, and then use the Raspberry Pi to select a random LED color and intensity. The tutorial also discusses designing a protocol for message exchange, handling commands, and converting strings to integers for LED control. The Raspberry Pi acts as the brain, deciding actions, while the Arduino serves as the muscle, executing commands. The video concludes with an overview of how these components work together in various projects.
