Re-load stop
Since the accelerometer was placed on top of the dart holder, it record the acceleration o the xyz axis as it is returning and launching.
In its re-laod position the accelerometer Z values read between 0.3 and 0.6, the Z values read between 0.6 and 1.0, the x-readings were out of plane motion. So when the sensor reads the position, the motor will stop for 3 seconds, then a signal for full speed is sent. Then it goes back to its feedback loop.
