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.

//if the tech puts a little hot air over the temp sensor it will raise to at least 170
digitalWrite(ledPins[5], LOW); //Turn on red LED – to indicate &quot;hot&quot;
digitalWrite(ledPins[5], HIGH); // turn the red LED off

/* from here on down, we’ll just print out the status of every input */
