Web. This is a fork of Adalight working with WS2811/WS2812 LED using the last version of FastLED. :bulb: - GitHub - Wifsimster/adalight_ws2812: This is a fork of Adalight working with WS2811/WS2812 LED using the last version of FastLED. Web. I did it with a colour detector module. I put it at the top middle of the TV, just hanging over (peering down at the screen). It picks up only one area of the screen and uses that across the top, but that's kinda where you're looking when you notice it anyway..
The ws2812b led strip is cheap, can be attached onto a esp board that act as a controller and with some open-source software flashed to it, the possibilities are endless. Several ideas popped up: Parking sensors, DIY Ambilight, lights that react on music, lights with messages on it, DIY LED lights that acts as HUE's or candles. Web. Web. Web.
Newer WS2812B LEDs also use just three wires for control (power, data, and ground) while the WS2801's require four wires (the three above + clock). The lack of external signal circuitry and needing one fewer wire means that WS2812B strips can have more LEDs per meter and are slightly smaller.
