I think you need a bit-shifter like this:

I bought a package for my raspberry and it was with the matrix display.

Reason: you have 8x8 = 64 pins on that led but only "7 or 8" pins on your arduino (I assume) = You can address one row only. Good luck

See this https://www.b4x.com/android/forum/threads/74hc595-shift-register-for-multiple-output.71531/ for code example, the code is for color matrix so yours should be simpler.
