My computer science teacher and I are trying to make and program an led matrix, (possibly like 5 X 5 or a little bigger). We started off with a scrolling 1 X 5 led matrix, but that the letters were pretty difficult to read and it was too simple, so we moved on to a srolling 2 X 5 matrix. However, that was still pretty dificult to read and didn't look great either. Neither of us have much experience with the hardware for excedding the maximum number of output pins.
