Control LED Brightness with a Potentiometer | Arduino Beginner Project

In this video, I show how to control the brightness of an LED using a potentiometer and an Arduino Uno. By turning the potentiometer knob, the LED gets brighter or dimmer using PWM (Pulse Width Modulation).
This is one of the best beginner projects for learning how analog input and PWM output work in Arduino.
