LED strip/ bulb driver module

[J-M-L]

search a bit in the forum, there have been discussions in the past of driving RGBW strips

here is one

RGBW LED Strip with generic controller (f.e. SK6812RGBW)

It is working now. I forgot to connect the ground of my Arduino to the ground of my power supply for the LEDs, so the data signal had no common ground reference with respect to the power, thats why my lights were flickering and displaying random colours. My bad. :-[ And yes, the SK6812 I got are the RGB type, not RGBW. I used the NEO_GRB and it works perfectly.
