Hello!
In school i recently gotten a project in which we gonna do a simple 4 in row game. I did some of the code but cant get my matrix to work with certain button. I got a 8-5 Led matrix and declared button to pin 13-9 , The pin 13 worked exatly as intended and does it work but none of the other pins does. When i click the right button i can fill out that row of lamps but whenever i click on any other of the lamps everything disconnects. Even through i have exatly the same code as the right lamp.
Heres the code :
