<p>Raspberry Pi Pibrella output node. The Pibrella board must be fitted.</p>
<p>Will set the selected output high (on) or low (off) depending on the value passed in. Expects a <b>msg.payload</b> with either a 0 or 1 (or true or false).</p>
<p>The Buzzer is a divider so low numbers are high notes. 0 is off, and the sensible lowest note is around 250-300. 2 is the highest note. 1 is just a buzz (so you can use 0/1 type inputs).</p>
<p><b>Note:</b> Using the buzzer is known to "kill" audio output via the 3.5mm socket.</p>
<p>Requires the WiringPi gpio command in order to work.</p>
<p>In PWM mode you can dim the onboard LEDs - expects a number from 0 - 100 (%).</p>
<p>The Buzzer takes a number in Hz (up to about 4000), or 0 for off, and 1 is a shortcut for 262.</div></p>
