        Pin 0: Program button used for recording a new Knock (connect Pin0 -> button -> GND) 
        Pin 1: Optional: Connect LED here (remember resisor in series)
        Pin 2: Optional: Piezo element (for beeps). 
-       Pin 1: A sound sensor (digital output) for sensing knocks. See MySensors purchase guide.
