<p>Raspberry Pi-LITEr output node. The Pi-LITEr must be fitted.</p>
<p>Operates in one of 5 different modes :</p>
<ul>
<li>Byte Mode - expects a value between 0 and 255, and each of the LEDs represent 1 bit.</li>
<li>Meter Mode - expects a value between 0 and 8, the led lit corresponds to the input value - like a meter needle.</li>
<li>Bar Mode - expects a value between 0 and 8, similar to meter - but all the leds up to the value are turned on - like a mini bar chart.</li>
<li>Object Mode - expects a object specifying the LED and state eg. <code>{led:3,state:0}</code> to set LED3 off.</li>
<li>All LEDs Mode - expects a 1 or 0 - turns on and off ALL the LEDs.</li>
