I'm making a 5x5 matrix and I want to power it with a 12v battery. My problem however is that each LED as I understand is in parallel, and the way I have wired it is with 1 resistor per LED. So that's 25 resistors. But now if I power 1 LED with a 12v battery and a 600ohm resistor I get 0.2watts of p…

5x5 led matrix power help?

Ok, then use TPIC6B595, can sink current from 12V source.
