Hi all I'm new to arduino (had some expierence with an arduino uno), but not with led strips yet so I wanted to try.
I saw some amazing ambilight projects online featuring an adruino togheter with some led strips on the back of a pc screen to emit colors of the screen.
So I went ahead and bought the required hardware on Aliexpress. But I have a problem: I can't get the led strip to work (somehow I got 1 individual led to go on, but there it stopped).
I used the the adafruit neopixel library (strandtest.ino) to test the strip.
I bought these led strips (2m 60 ip67): Led strips (Aliexpress)
