Circuit Diagram

Wired 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.

  • Positive from LCD to Resistor
  • Negative from LCD to Resistor
  • Resistor to female JST connector
  • Switch to Positive wire of JST
  • Battery to female JST connector

Battery Power

The circuit will be powered by a 3.7V 100mAh Lithium ion battery via JST connection. The battery plugs directly into the JST slide switch adapter.
