This project shows how to control Fading LED Circuit using Arduino and Potentiometer. Potentiometer gives analog voltage. By rotating the potentiometer knob varies the voltage output and arduino reads this variation. Arduino reads it and changes LED brightness and this LED brightness changes smoothly. It is easy to make a simple project for beginners and […]
