This project is a simple LED dimmer circuit that uses Arduino's PWM (Pulse Width Modulation) capability. The user can smoothly adjust the brightness of an LED using a potentiometer or digital input.

The TU-DO dimmer can control all three color channels of an RGB LED strip as well as optionally the brightness of a main 12V white LED strip using a set of 4 rotary potentiometers. In addition to ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...
