/*
Analog input, serial output
Reads an analog input pin, prints the results to the serial monitor.
The circuit:
* potentiometer connected to analog pin 0.
Center pin of the potentiometer goes to the analog pin.
side pins of the potentiometer go to +5V and ground
created over and over again
by Tom Igoe and everyone who's ever used Arduino
This example code is in the public domain. It's practically in the collective unconscious by now too.

// wait 10 milliseconds for the analog-to-digital converter

Calibration
Demonstrates one techinque for calibrating sensor input. The
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 minumum and maximum initial values may seem backwards.
The sensor minimum and maximum initial values may seem backwards.
Initially, you set the minimum high and listen for anything
lower, saving it as the new minumum. Likewise, you set the
lower, saving it as the new minimum. Likewise, you set the
maximum low and listen for anything higher as the new maximum.
