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.

What is the purpose of defining a constant for the LED pin in the code?

Explain the process of setting the mode of the pin in the code.

What commands are used to change the state of the LED pin?

How does the program make the LED blink after powering it on for three seconds?

Describe the sequence of actions taken in the loop function to achieve the blinking effect.
