ambibulb 0.0.4rc2

Raspberry PI utility that controls color of your IR LED light bulb based on the dominant color of the currently played video

AMBIBULB

Ambibulb attempts to provide the similar experience to Ambilight® (Philips TV's feature that projects color onto the wall behind a TV) using Raspberry PI and a simple IR remote controlled LED light bulb. Please watch the demo.

ambibulb can play a video and simultaneously transmit IR signal to the light bulb with its most dominant color. This can enhance your viewing experience or make your party more colorful 🌈.
