  This is example code for the Protosnap LilyPad Development Platform
  It'll do a quick startup sequence, flashing all LEDs, then it'll go int the loop.
  In the loop it'll check for button or switch presses, and buzz or vibrate
  depending on if they're engaged.
  If neither switch is on, it'll check the light sensor and temperature sensor,
  and light up some LEDs if the proper values are met. Hold your finger over the
  light sensor to turn the white LEDs on. Try blowing on the temperature sensor to
  turn the red LED on.
  Finally, the status of each input is streamed over the serial line at 9600 bps.
  To see what the values are, open up the serial monitor (the top right icon)
  and make sure the baud is set to 9600.
