But how to control it?
Ah, that's not what I thought you meant. Try these !www.allegromicro.com/en/Products/Part_Numbers/6278/ Use them on, say, the columns, and use 74HC595 latches and then www.allegromicro.com/en/Products/Part_Numbers/2981/index.asp for the rows. You can mess around with transistors and serial latches, but its not worth the hassle. I assume you are aiming to use an arduino to drive it ?
