Circuit Diagram

GEMMA + NeoPixels

Follow the circuit diagram above to get a visual reference of the wiring. The NeoPixels are connected together in a chain, sharing power, ground and data. Two tactle monentary buttons alternate between color modes and activates a firing animation sequence. 

Position and Placement

The placement of the components in the diagram are not exact. This is an outline of how the components are wired together. In the final circuit, the 12x NeoPixel ring will be positioned inside of the 24x NeoPixel ring, over the GEMMA.

Power

To power this circuit, use a battery with a JST male connector. The GEMMA has a female JST connection on board. In this project, we're using the AAA battery holder with on/off switch.
