Does anyone know how to keep the large Neopixel LED on the GEMMA M0 board turned off?
Hello everyone , Does anyone know how to keep the large Neopixel LED on the GEMMA M0 board turned off? It consumes energy for nothing, but in all the code examples I've seen, there's nothing for this LED... Thanks in advance.

hey camilla, by Setting all the pixel colors to to 0,0,0 will turn off the LEDs. There will still be a small amount of current consumed
Switching off power completely would be tricky. Neopixels are fairly sensitive to conditions such as the control signal voltage exceeding VCC, You would probably need to make sure that both signal and VCC were turned off. Switching from the low-side only does not work: http://forums.adafruit.com/viewtopic.ph...
