  This example demonstrates the use of  while() statements.

  While the pushbutton is pressed, the sketch runs the calibration routine.
- The  sensor readings during the while loop define the minimum and maximum 
+ The  sensor readings during the while loop define the minimum and maximum
  of expected values from the photo resistor.

  This is a variation on the calibrate example.

  The circuit:
  * photo resistor connected from +5V to analog in pin 0
  * 10K resistor connected from ground to analog in pin 0
  * LED connected from digital pin 9 to ground through 220 ohm resistor
  * pushbutton attached from pin 2 to +5V
  * 10K resistor attached from pin 2 to ground
