Here’s a handy hack for an Android controlled, Arduino driven, RGB light setup. [Kerimil] recently wrote up this project on the Arduino.cc, and is sharing all of the source code and plans. While many ...

When we see RGB LEDs used in a project, they’re often used more for aesthetic purposes than as a practical source of light. It’s an easy way to throw some color around, but certainly not the sort of ...

Using a little electronic programming, hardware and of course 3D printing technology, James Bruton has created a new gyroscopic lead-controlled RGB LED ball. Check out the demonstration video below 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 ...
