I just want my clear seimitsu button(the guide button) to stay lite when the controller is connected. I know the late wired 360 controller is 5v. So what size LED and resistors do I use that is the only thing im unsure of? Also do I just run the 5v and a ground to it? and I take it the resistor go’s between the 5v and the led?
As for what to use… http://ledcalc.com/
You’ll want to wire it up in PARALLEL so it would go 5v->resistor->led->ground for each LED. I suggest buying a barrier strip to make it easier/cleaner rather than having to solder 6 or however many resistors you have to the 5v, and the same with ground. You would still use the same resistors/LEDs used in TingBoy’s guide (1/8W 220ohm-2.2kohm depending on how bright you want it to be).
