API summary

The DigitalOut Interface can be used on any pin with a blue label, and also with the on-board LEDs (LED1-LED4)

The DigitalOut Interface can be used to set the state of the output pin, and also read back the current output state. Set the DigitalOut to zero to turn it off, or 1 to turn it on.

See the Pinout page for more details
