ATTiny Capsense LightSwitch

#include <CapacitiveSensor.h>

/*
 * Based on the CapitiveSense Library Demo Sketch
 * which was written by Paul Badger 2008
 * Uses a high value resistor (in this case, 750k ohm) between send pin and receive pin
 * Resistor effects sensitivity, Larger resistor values yield larger sensor values.
 * Receive pin is the sensor pin
 - Final sketch written by Brian Schulteis - The UnaClocker, November 2013
 - Uses an ATTiny85 running at 8MHz on the internal oscillator, to control an XBox 360 power supply
 - 5v is provided by the 5v standby power of the XBox 360 power supply.
