Hi guys
I want to do a new mod on a xbox 360 controller. I have a matrix controller and i have bought a clear cases. I will put over 20 smd red leds in on the front and 10 in the back. I am going to put all in series to have only two wires in front and two wires in the back.
Then I have an issue. What resistor and how much i need?? Also I would like to put a dyp switck to turn it on and off when i want but i have never use it one. It would be like a normal switch?? I mean, positive of leds would go to the DYP switch and then to the mobo and negative directly to the mobo??
This is what i want to do moreless:
