My LED matrix isn't working?
I made 10x9 LED matrix so far. I wanted to make music analyzer. But I got a problem.
My whole matrix is mixed up. Columns and rows are connected propertly. When i connect row 2 and column 3, for example, 10 random LEDs are light up(they are always the same.). Also, i can connect positive pole to chatode or anode, both way LEDs will light,
What could be a problem? I was looking for burned LEDs and changed them(there was only two).
I'm so confused.
Thanks in advance.
