  //   Serial1 = name of serial port (usually Serial1 or Serial2).
  // With these parameters, up to 10 files may be played on pins 10000-10009.
  // Play is started from EX-RAIL with SET(10000) for first mp3 file, SET(10001)

  // value to the first pin, e.g. ANOUT(10000,23,0,0) will play the 23rd mp3 file.
  // ANOUT(10000,23,30,0) will do the same thing, as well as setting the volume to 
  // 30 (maximum value).
  // Play is stopped by RESET(10000) (or any other allocated VPIN).
  // Volume may also be set by writing an analogue value to the second pin for the player, 
  // e.g. ANOUT(10001,30,0,0) sets volume to maximum (30).
  // The EX-RAIL script may check for completion of play by calling WAITFOR(pin), which will only proceed to the
  // following line when the player is no longer busy.
  // E.g.
  //    SEQUENCE(1)
