<p>Raspberry Pi input node. Generates a <code>msg.payload</code> with either a
0 or 1 depending on the state of the input pin.
Requires the <a href="http://abyz.co.uk/rpi/pigpio/pigpiod.html" target="_new">pi-gpiod</a>
daemon to be running on the host computer in order to work.</p>
<p><b>Outputs</b>
<ul>

<li><code>msg.topic</code> - <i>string</i> - pi/{the pin number}</li>

<p>You may also enable the input pullup resistor &uarr; or the pulldown resistor &darr;.</p>
<p><b>Note:</b> the pin numbers refer the physical pin numbers on connector P1 as they are easier to locate.</p>

<li><code>msg.payload</code> - <i>number | string</i> - 0,1 (Digital), 0-100 (PWM, Servo)</li>

<p><b>Details</b></p>
<p>Digital mode expects a <code>msg.payload</code> with either a 0 or 1 (or true or false),
and will set the selected physical pin high or low depending on the value passed in.</p>
<p>The initial value of the pin at deploy time can also be set to 0 or 1.</p>
<p>When using PWM and Servo modes, the input value should be a number 0 - 100, and can be floating point.</p>
