Connections

The circuit diagram above shows how the components will be wired together. This won't be 100% exact in the actual circuit but it's a very close approximation. Please note the buttons connected to the capacitive touch sensor do not have to be buttons. They can be any piece of electrically conductive material.

Battery Power

The circuit will be powered by a 3.7V 2500mAh Lithium ion battery via JST connection. The battery plugs directly into the Adafruit Feather 32u4 Bluefruit LE, which allows had a built-in charging circuit so you can recharge the lipo battery over the microUSB port.
