Thanks to Tobias for sending in this Ambient Lighting project! Check out more here.
After buying a new TV set, I started missing the Ambilight feature of the previous Philips TV.
Doing some research on how to possibly replace it, I’ve had the idea of combining existing components – hardware and software – to create something similar for this purpose. Controlled by an Arduino, a RGB sensor placed in front of the TV picture will detect the color of a particular area of the screen, which will then be used to set the color of an entire NeoPixel strip, resulting in a constantly adapting ambient lighting.

RGB Color Sensor with IR filter and White LED – TCS34725: Your electronics can now see in dazzling color with this lovely color light sensor. We found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The filter means you’ll get much truer color than most sensors, since humans don’t see IR. The sensor also has an incredible 3,800,000:1 dynamic range with adjustable integration time and gain so it is suited for use behind darkened glass. Read more.
