Type: Input, Pull Up
Type: Input, Pull Down
Use: Start pin. If this is active, the game starts.
pin_stop
Type: Input, Pull Up
Type: Input, Pull Down
Use: Stop pin. If this is active, the game ends
pin_error
Type: Input, Pull Up
Type: Input, Pull Down
Use: This is to be attached to the game wire. If the wire is touched,
the pin is pulled up and an error is registered.
pin_shutdown
Type: Input, Pull Up
Type: Input, Pull Down
Use: Triggering this input causes a system shutdown.
