/* Monster Motor will set a motor going in a specific direction
  the motor will continue turns in that direction, at that speed
  until told to do otherwise.

  Motor: this should be either 0 or 1 will selet which of the two motors to be controlled

  Direct Should be between 0 and 3, with the following result

  0 - Brake to VCC
  1 - Clock wise
  2 - Counter Clockwise
  3 - Brake to GND

  PWM (Pulse with Moduleation) should be a value between 0and 1024, higher the number, the faster turns
