Next Question: 433Mhz type tx/rx?

[kresty]

Lots of the 12 button remotes basically use something like this:

What I'm wondering how to hook up the RX directly to an Arduino or something?  Seems like if you could pass data in and get data out, then that'd be way easier than doing the dozen relay type thing on the other end.  Of course maybe you'd have to figure out interference with other devices, etc.

So, is there a way to "easily" create a signal on the TX end and "see" that signal on the RX end?
