[QUOTE="kenwonders, post: 1065180, member: 29743"] I feel for ya HomeY, it took me 4 days to get a colour out of them that I had actually asked for. If you have covered power and direction, looks like your next culprit is the addLEDS call, perhaps try different settings there like addLeds<WS2812, DATA_PORT, GRB>(leds, NUM_LEDS); or change WS2812 to WS281_400 which according to the FastLED header is the 400khz version of the same thing: [CODE] case WS2812: case WS2812B: case WS2811: { static WS2811Controller800Khz<DATA_PIN> controller; return addLeds(&controller, data, nLedsOrOffset, nLedsIfOffset); } case NEOPIXEL: { static WS2811Controller800Khz<DATA_PIN, GRB> controller; return addLeds(&controller, data, nLedsOrOffset, nLedsIfOffset); } case WS2811_400: { static WS2811Controller400Khz<DATA_PIN> controller; return addLeds(&controller, data, nLedsOrOffset, nLedsIfOffset); }[/CODE] if you have the RGB order wrong, this will just mean the wrong colours (or it did for me), so I'd worry about that once they light up at all.
