Awesome!
well so I thought lol. It worked perfectly in the breadboard. then I soldered it up, and now when I turn off the psu (or unplug it) it doesn't take 5v away from the sense pin again, but it worked perfectly in the breadboard! :? I've gotta mess with it this weekend and see if I can figure out why :?
got it. stupid error on my part lol. I had an extra 5v line going to the arduino power from the 5v psu line. this was keeping voltage flowing through the relay. all set :D
