This diagram uses the original Gemma but you can also use the Gemma M0 with the exact same wiring!

Three of the sequins connect to D0 and the other three connect to D2. The sequins are connected in parallel to these pins.

The original version of this project used D1 also, but since the Gemma M0 does not have PWM on this pin, we've tweaked it a bit to only use D0 and D2!
