2015-04-06 (M) Self Contained Haptic Distance Sensor

A 5V Arduino replaced the 3.3V Arduino to try to eliminate the unreliable operation of the distance sensor. When the new Arduino was in place the problem did not disappear but the distance sensor acted predictably when the ECHO wire from the distance sensor was held taut. Two solid copper wires replaced the wires in place. This could have been the root problem. More testing is necessary to determine if the problem has been fixed. Powering the device is now done through the 1.3mm x 3.5mm socket or the data pins but the 1.3mm x 3.5mm USB cord has not arrived so the device can only best tested with the data pin power connected.
