  • So I wired the WS2812B to the Espruino. up to the WS2812B strip, but I can't get it to do anything other light up completely.

    I used the first line of test code which is:
    require("neopixel").write(B15, [255,0,0]);

    But the code doesn't even to take effect.

    Wiring diagram as per below. Note that the power source is a 4xAA battery pack which is delivering 5.3v. I get that 4xAAs can't power a whole strip, but they should power one LED.

    What am I doing wrong?
