API
Scop()
A class that instanciate a serial port communication with the arduino. When the serial port is opened, it sends a 'ready' event.
Scop.play(sequence:Array, bpm:Number)
Play sequentially the motors. The sequence provided is an array of motorID (i.e from 1 to 4). If you put a 0 on the array it means no motor will be played during the measure. When the sequence is finished, an event is sent.
