Digital Input
1 of 2 identical circuits shown
Digital Inputs have a pull-up resistor to 3.3v and will operate with a simple contact closure to ground.
Alternatively, they may be connected to 3.3v logic. The clamping diodes prevent operation at voltages
higher than 3.3v, so don’t connect to 5v logic.
