    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
