Connects to local Arduino and monitors the selected pin for changes.
You can select either **Digital**, **Analogue**, or **String** input type.
You can select either **Digital**, **Pullup**, **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. For example you could use a `delay` node set to rate limit and drop intermediate values, or an `rbe` node to only report when it changes by a certain amount.
