How can I send a signal to LEDs from my Android 4.2.2 device? (Eclipse & USB cable)

Question

I am trying to use my Android 4.2.2 in order to illuminate my LED circuit. I can do this with y microprossessor, so why couldn't do this with Android? I want to touch a button than make an open signal, then send this through the USB cable to my LED circuit.

I am electronics engineering student. Is there any Android codes to do this?

Answer 1

Are you on about controlling your LED by perhaps holding Data+ USB pin high or something like this? http://android.serverbox.ch/?p=549
