This software part installs on your Arduino UNO and works with Ambilight for MacOS
Ambilight (Ambient Lighting Technology) is a background lighting technology for televisions that was invented and patented by Philips Electronics.
If you don't have FastLED library installed in Arduino IDE
Tools -> Manage Libraries -> FastLED -> install (worked with 3.3.2)
Add Library to the project
Sketch -> Include library -> FastLED
If you have RGBW (RGB+White) Leds use that library: https://github.com/sosiskus/FastLED-with-RGBW-leds
Configure NUM_LEDS
(number of addressable leds)
Change DATA_PIN
to that one you want to use.
You have to know your Chipset FastLED.addLeds(YOUR_CHIP_HERE, DATA_PIN, YOUR_RGB_ORDER_HERE)
Led strip uses much power so that's why it's impossible to user the same power Arduino uses. U need to connect another power supply (for exmaple, use one more usb cables (without data connection!!!))
