Electronic Circuits - LED Dimmer Circuit - Brightness Control Using a Potentiometer

This electronics video tutorial explains how to design a simple LED dimmer circuit. The brightness of the light emitting diode can be controlled using a variable resistor known as a potentiometer. The series current limiting resistor serves to protect the LED from excessive current flowing through it.
