So in my project for bingo its going pretty good. I am one step closer to having it work. So when I hit a row button and a column button the arduino will turn on an led to the max7219. The only problem is that when i turn on more then one light in the same row the max shuts the previous led off and …

Guidance needed on how to light up many lights on one column of max.

So I kinda get this more now but where would my variables rowstate and columnstate go?
