* CapitiveSense Library Demo Sketch

* Paul Badger 2008

* Uses a high value resistor e.g. 10M between send pin and receive pin

* Resistor effects sensitivity, experiment with values, 50K - 50M. Larger resistor values yield larger sensor values.

* Receive pin is the sensor pin - try different amounts of foil/metal on this pin
