I wanted to build myself an Ambilight Background for my Monitor using:
-WS2812 12V Addressable LED Strip
-12V Power Supply (for now a battery, because the LED Strip needs more Power than expected)
-Bambilight by MrBoe ( GitHub - MrBoe/Bambilight: A simple implementation to send the colors from a Windows-PC-Screen to a LED-Strip over Arduino. Maybe some people would call it "Ambilight" ;) )
I connected everything according to the Tutorials, but the LEDs don't light up.
The FastLED Library is installed and the sketch is uploaded (Port/Boardtype/etc. should be right).
I checked the Voltage at the battery and at the end of the strip and 12V are supplied.
If anybody got an idea, I'd be glad
