The accelelerometer is placed on the arm in which the diamond is attached durring the diamond polishing process, and when the acceleration measure spikes beyond a threshold limit, set in the code on the Arduino, in any direction(x, y, or z), an alarm is triggered by a digital output pin of the Arduino to alert the operator of a flaw.
