An important safety precaution here is to wire a 1M resistor in series with
the wire from the alligator clip to ground.  It is possible to 
accidently become a conductive path from a high voltage (ie 110V A.C.)
to ground if you touch something you shouldn't. Without the resistor
you are taking a VERY big risk.  Safety First!
