/* This code simply prints out the value of a potentiometer
 * on an analog pin. The potentiometer should have one side
 * to 5V, one side to GND, and the middle to analog in
 * pin 0. Once the sketch is uploaded, open the serial monitor
 * (top right button) to view the reading.
 * 
 * Look at the Arduino site reference page and the description of
 * the 'if...else' operator under the 'Structure' section. Use
 * this operator to also print 'left' or 'right' if the pot is
 * turned either side of the halfway mark:
 * https://www.arduino.cc/en/Reference/HomePage
 * 
 * The code is heavily commented to describe exactly what is going on
 * and all the other bits you need are there. Watch out for getting your
 * curly brackets in the right place and making sure you close them correctly. 
 * Check the error messages if things don't work!
