DPST button and function

A double pole single throw push button micro switch (DPST) is a widely used button. Push button switches are often color coded to indicate their function.

Three methods to wire

  1. Internal resistor: Use INPUT_PULLUP in setup pinMode( Button_pin, INPUT_PULLUP);
  2. The bad method:
