Raspberry Pi and Arduino - Go to The Next Level - Step 4 (Arduino) - Get Commands from Serial and Execute Them

The video tutorial explains how to handle serial commands for controlling hardware components like servos, LCDs, buzzers, and LEDs. It covers initializing components, processing commands using if-else structures, and testing the code on Arduino. The tutorial also discusses best practices for handling errors and improving code efficiency.

What are the steps taken to ensure that the commands are executed correctly on the hardware?

How does the program differentiate between different commands like 'play buzzer' and 'set LED'?

What is the significance of the command 'set LED' in the program?

Discuss the role of the Raspberry Pi in the overall application as described in the text.
