 the motor will continue going in that direction, at that speed

 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: Clockwise
 2: CounterClockwise
 3: Brake to GND
 
 pwm: should be a value between ? and 1023, higher the number, the faster
