+You can select either **Digital**, **Analogue**, or **String** input type.
 Outputs the value read as `msg.payload` and the pin number as `msg.topic`.
 
 It only outputs on a change of value - fine for digital inputs, but you can get a lot of data from analogue pins which you must then handle.

 Expects a numeric value in `msg.payload`. The pin number is set in the properties panel.
