Hi, I was told that this is the place to ask my questions 
I set up my Odroid C2 with an Adruino and Adalight. It seems to be connected correctly (at the startup the led light up 2x and then there comes on one of the effects) I have it connected correctly but when I start a movie or watch tv - nothing happens - if i play the radio or sound and the visualisation comes on the ambilight works… so i guess the grabber is somehow broken?
Where could my problem be? Thank you all for helping
