    <p>Arduino input node. Connects to local Arduino and monitors the selected pin for changes. Uses <a href="http://firmata.org/" target="_new"><i>Firmata</i>.</a></p>
    <p>The Arduino must be loaded with the Standard Firmata sketch available in the Arduino examples.</p>
    <p>You can select either Digital or Analogue input. Outputs the value read as <b>msg.payload</b> and the pin number as <b>msg.topic</b>.</p>
    <p>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.</p>
    <p>You can set the sample rate in ms from 20 to 65535.</p>
