Can someone help me please. I managed to get de Arduino working with the WS2812B leds and Boblight. For some reason Enigmalight won't work.
Because it didn't work completely like I would I played a little with all the settings and at one moment it stopped and what ever I tried it won't start again.
I Use this bob light.conf file (the original files won't upload, no permission)
#[global]
#interface 127.0.0.1
#port 19333
[device]
name ambilight
output /dev/ttyACM0
type momo
channels 387
interval 20000
prefix 53 74 65 66 61 6E
rate 500000
#debug off
delayafteropen 1000000
And this sketch I found on the arduino forum

These worked for me. The sketch is working for me when I changed the color or the brightness but the bob light program doesn't manage to sent signals to the arduino.
