/******************************************************
*               The Proximity Sensor Game
* Rules of the Game:
* 1. Get your hand to match what the sensor indicates. A 20 will mean that the your hand needs to be close to the sensor. A 50 will mean that your hand needs to be farther away. 
* 2. The goal is to reach 5 points.
* 3. Once you hit 5 points, your time will be shown on the LCD. Challenge your friends to see who gets the lowest score!
