Raspberry Pi For Beginners - 2022 Complete Course - Activity 04 - Set the LED's State from User Input

The video tutorial explains how to control an LED using user input, where the input can be either 0 or 1. If the user inputs 0, the LED is powered off; if 1, it is powered on. The tutorial covers setting up the LED as an output pin, obtaining user input, and storing it in a state variable. It also discusses validating the input using conditional statements and handling invalid inputs by printing an error message, cleaning up GPIOs, and exiting the program. The lesson concludes with a brief overview of the next steps.
