#include < LedControl.h>  //Import the library

#define DELAY 10 //Sets the delay between each frame in mS
#define NUMBER_OF_DISPLAYS 1 //Sets the number of display (4 for this example)

/*
Initialize the library. The 4 means that the CS pin is connected to pin D4.
You can change this to whatever you want, just make sure to connect the CS
pin to the pin number.

The disp means that any future function calls to the library uses "disp" as the
library's object name. For example, the library has a function called
"setIntensity", you need to write "disp.setIntensity" to call that function.

If you notice that the display is upside-down per display, change 
simpleMatrix disp(4, false, NUMBER_OF_DISPLAYS); to simpleMatrix disp(4, true, NUMBER_OF_DISPLAYS);
