Install this library before trying to run your code!

Code:

/* To install this library, go to
  Sketch --> Include Library--> Manage Libraries
  now search for "LedControl"
  Choose install
*/
#include "LedControl.h"

LedControl lc = LedControl(12, 11, 10, 1);
/* we always wait a bit between updates of the display */ unsigned long delaytime = 500;
void setup() {
  /*
    The MAX72XX is in power-saving mode on startup,
    we have to do a wakeup call
  */
  lc.shutdown(0, false);
  /* Set the brightness to a medium values */  lc.setIntensity(0, 8);
  /* and clear the display */
  lc.clearDisplay(0);
}
