Constructors

Constructor and Description
GpioLEDComponent(GpioPinDigitalOutput pin) default constructor; using this constructor assumes that: (1) a pin state of HIGH is LIGHT ON (2) a pin state of LOW is LIGHT OFF
GpioLEDComponent(GpioPinDigitalOutput pin, PinState onState, PinState offState) using this constructor requires that the consumer define the LIGHT ON and LIGHT OFF pin states
