Firmata Digital Input Pullup Channel¶
Description¶
Digital input pullup channel on a Firmata Device.
Unlike a standard digital input channel, a digital input pullup channel enables the built-in pullup resistor for its associated pin. This causes the input to be high/true when unconnected and low/false when connected to ground. For more information, see the Arduino documentation on digital pins.
