Arduino for Beginners - 2022 Complete Course - Set a Digital Value - Power On an LED

The video tutorial explains how to set up an LED on pin 12 using a microcontroller. It covers defining constants for easy pin access, setting the pin mode to output, and writing a program to make the LED blink. The tutorial includes steps for configuring the pin, setting initial states, and implementing a loop for blinking with delays. Finally, it demonstrates uploading and executing the program to observe the LED behavior.
