   // Set the background color of the LedDisplay
   ledDisplay.setBackgroundColor(new Color(51, 51, 51));
   
   // Set the color of a turned off dot
   ledDisplay.setDotOffColor(Color.BLACK);
   
   // Set the dimensions, in pixels, of the display's led
   // Default values are (1, 1). 
   ledDisplay.setDotSize(2, 2);
   
   // Set the gaps, in pixels, between two display leds.
   // Default values are (1, 1). 
   ledDisplay.setDotGaps(2, 2);]

   //                   LedDisplay.SOUTH
   //                   LedDisplay.NORTHWEST
   //                   LedDisplay.NORTHEAST
   //                   LedDisplay.SOUTHWEST
