THE CODE SUCKS. I JUST WANTED THE DISPLAY TO WORK AND NOTHING MORE. THERE WERE TONS OF WAYS WHERE IT COULD HAVE BEEN BETTER. I TOOK BAD STEPS AND I AM AWARE! Many parts of the code gets repeated, there is a lot of debugging to do and I could have just use the bitshift operators (>> and <<) for the rows. I didn't choose to do it for some reason so the code sucks. I don't recommend you look at it at all haha.

This is the code and the general description for an LED matrix project I personally have been working in. The project is yet to be completed and I intend to add more to it. The code is amateur-esque as I have near none experience on arduino currently. I was interested in the project and picked up the idea.

Here one of the columns is dead. This was because of the terrible soldering. I hope to manage it at some point in the coming month

This is printing the letter S but since one of the columns is dead along with another one pixel, it looks odd. It should be showing S

This is the final product after fixing most things. Some of the lEDs are dead and I haven't used resistors, so the life of the LEDs won't be very good. But the project is done!

The Circuit looks messy but it was fun to work with! The project was for me to learn about something new and this genuinely satisfies me.
