So I extended a wire upstair, thinking I could tap into to signal serially just adding a resistor(it's 12v). uhhh.

But then I realized I would never get anything from that setup, unless I would tap into the line serially with a relays.
So I wonder know, is there a *simple*, electronic way(else than a relay) to get a 5v signal from that setup??
Some kind of ghost current detection?
thanks to the knowedgeables!

Wireless doorbell from Walmart or something... $10, runs for a couple of years off 2 AA's, range of a 100 feet or so. Mine was a bit loud, muffled it with duct tape internally (after all, what CAN'T duct tape do). And it has an on/off switch when I just don't want to listen to it.
Now THAT is simple.
