The circuit diagram here is setup for testing and prototyping with two LED buttons and one arcade button. Get one or two buttons working first and then add more!

You will need to add buttons and neopixels in series in the complete build.

Additional buttons all have one side of the switch connected to ground (you can wire them all to each other and then to a ground pin) the other side of the switch goes to the button # inputs on the right side of the Bluefruit EZ-Key. For the LED lit buttons, connect a 220-1000 ohm resistor from the LED- pin to ground and the connect all LED+'s together to 3.3V
In our finished build, you can see we have the resistors closer to the LED push buttons. The thick strand of wires are routed through the opening of the two pieces where they join together.
