   Calibration

  Demonstrates one technique for calibrating sensor input.  The
  sensor readings during the first five seconds of the sketch
  execution define the minimum and maximum of expected values
  attached to the sensor pin.

  The sensor minimum and maximum initial values may seem backwards.
- Initially, you set the minimum high and listen for anything 
+ Initially, you set the minimum high and listen for anything
  lower, saving it as the new minimum. Likewise, you set the
  maximum low and listen for anything higher as the new maximum.

  The circuit:
  * Analog sensor (potentiometer will do) attached to analog input 0
  * LED attached from digital pin 9 to ground
