I've got a bunch of physical switches and circuits that act like switches (they're either connected to ground or they're just an open wire). Is there some sort of thing I can plug into my computer (ideally, via USB) that has a bunch of screw terminals, and I can attach wires to the screws and have the computer keep track of which circuits are closed and which are open?

Bonus points if the device also lets the computer open and close switches, too.

I don't even know what to google for.
