<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 mode - expects an input value of a number 0 - 100. It can be floating point.</p>
<p>PWM mode - expects an input value of a number 0 - 100. It can be floating point.</p>
<p>PWM mode can be used to drive a servo using input values between 10 and 20 only.
The GPIO2 pin is best for this as it uses hardware to do the PWM.</p>
<p>Setting high PWM frequency might occupy more CPU than expected (default is 100Hz)</p>
The GPIO2 pin is best for this as it uses hardware to do the PWM. For better servo support
consider the alternative node-red-node-pigpio node.</p>
