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.

What is the process that occurs when the push button on the Rhino side is pressed?

Explain how the Raspberry Pi chooses a random LED color.

Describe the steps the Arduino takes after receiving a command from the Raspberry Pi.

What is the significance of using 'command starts with' in the Arduino code?

How does the Raspberry Pi determine the color and intensity of the LED to be sent to the Arduino?
