- * 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
