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?

Serial between two Arduinos?

I can use RS-485 with max485 the same way as max232. right?
