I want to get one Arduino to talk another Arduino that's about 50 feet away. Can I use serial for this? I know RS232 has a distance of like 100 meters, but this isn't RS232. How would I wire it up? Just TX on one, to RX on the other?

More specifically I'd like to have a remote Digispark phone home to my main Arduino that's about 50 feet away. I play on running four wires between them: 5v, ground, TX, and RX. Is that workable?
