 *  Wiring
 *    RobotGeek Sensor Shield With Geekduino
 *      The RobotGeek I2C LCD will plug directly into the 4-pin I2C port on
 *      the sensor shield using a 4-pin sensor cable. Normally the sensor cable
 *      will be plugged in with the following orientation:
 *        SCL    - Yellow
 *        SDA    - White
 *        5v/VCC - Red
 *        G/GND  - Black
 *  
 *   Digital Input  2 - Pushbutton       
 *   Analog Input 0 - Rotational Knob
 *   Analog Input 1 - Joystick Horizontal
 *   Analog Input 2 - Joystick Vertical
 *
 *
 *  Control Behavior:
 *    The state of value of each sensor will be displayed to the LCD
 *    B:Button
 *    K:Knob
 *    X:Joystick Horizontal
 *    Y:Joystick Vertical
