Cheap DIY Ambientlight using Arduino

The Ambilight in this picture is completely DIY and uses some cheap RGB LEDs with integrated controllers and an Arduino. On the Software side, there is Ambibox running on the PC (Windows only) and the FastLED library on the Arduino! The Ambilight is totally DIY and easily bright enough so that no other light is needed. The screen is mounted to the wall and flushes with the table. (So no Ambilight at the bottom.)”
