Hi people,

I have small question. I got 5x5 led matrix. We can say it like 25 switches, or 5x5 matrix. So, how to controll it?
Probablly you will say to use PIC(Or Atmel), but try to not.

Thanks!
 

use 74595 [cascade ], this might be best option you may have , it will applicable for switches as well as for leds .
