Here, D11-D10-D9 pins of Arduino is used to drive the Red, Green, Blue Anodes of the common-cathode RGB LED (L1) through independent 270 Ohm current limiting resistors (R1-R3). Common cathode of the ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

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. Wh… ...
