Arduino LCD: Run on DFRobot LCD Shields.

Simon Baker (TinkerTronics) sent me the following code to get the Arduino game conversions running using the DFRobot LCD Keypad Shield. Just replace the relevant code at the top of the file and uncomment the #define DFROBOT_LCD line.

You'll notice that the ADC reading are slightly different. Enjoy!

// #define DFROBOT_LCD 

// Pins in use
#define BUTTON_ADC_PIN           A0  // A0 is the button ADC input
#define LCD_BACKLIGHT_PIN         3  // D3 controls LCD backlight

#ifdef DFROBOT_LCD
  // ADC readings expected for the 5 buttons on the ADC input
  #define RIGHT_10BIT_ADC           0  // right
