gpio out

Drives a GPIO pin high or low based on an incoming message.

Properties

  • pin — GPIO pin number. Checked against your board.

Behavior

Any truthy payload sets the pin high; anything falsy sets it low. Since the incoming wire can be any type, "truthy" follows Python's own rule (0, "", None, and False are falsy; nearly everything else is truthy) — a bool input works exactly as you'd expect, and other types convert sensibly too.
