The output node will set the selected output high (on) or low (off) depending on the value passed in. Expects a `msg.payload` with either a 0 or 1 (or true or false).
You may also select PWM mode to dim the on board LEDs if you wish. Expects a value from 0 to 100.
The Buzzer expects a number representing the frequency in Hz. 0 is off and 1 is a tone - so you can use 0/1 type inputs as well.
