This diagram uses the original Gemma but you can also use the Gemma M0 with the exact same wiring!
Connections are as follows:
- GEMMA D1 to 1st NeoPixel Jewel IN
- 1st NeoPixel Jewel OUT to 2nd NeoPixel Jewel IN
- GEMMA Vout to 1st and 2nd NeoPixel Jewel PWR
- GEMMA GND to 2st and 2nd NeoPixel Jewel GND
Strip, tin, and solder wires to the NeoPixel Jewels according to the circuit diagram. It's easiest to insert the wires from the front of the PCB and solder on the back, where there aren't any other components to bump into.
Be sure to leave enough slack between jewels to space your eyes out in your costume! Extra slack is ok, you can always tack it down with a needle and thread.
Solder long wires (at least 18 inches) between GEMMA and the 1st NeoPixel jewel according to the circuit diagram.
You can optionally diffuse the LEDs by covering them in white paper.
