I'm fairly new to using an arduino and i've been trying to get a project to display numbers to a 8x8 led matrix and i'm having trouble getting it to display. All i get is is just a flashing of random lights on the matrix or two columns just stay lit and no interaction between my arduino and the display seems to be happening. Any way someone could trouble shoot my code and see if its a code error?
Here is the code:
#include <LedControl.h>
