This Arduino project demonstrates how an analog input device can be used to control the brightness of an LED in real time. By rotating a potentiometer, the Arduino continuously measures the changing ...

This project shows how a potentiometer (variable resistor) can be used to control the brightness of an LED. The Arduino reads the analog value from the potentiometer and uses PWM (Pulse Width ...

Potentiometers are one of the most common input devices you’ll find in electronics projects. They’re often used to control things like audio volume, screen brightness, or even robot speed. In this ...
