It would be nice if we had a example of   a RF code lerner , so that it could receive RF code  (learn them ) then repeat them back via transmitting .
Lots of people  have RF remotes and that function would be useful  ( to me ) and I would think quite few other people .
Interesting but I was really keen on doing the same is this project

I am working on a jester sensor that would trigger a radio signal . The board ( transmitter is quite small)
( Micronised jewelry in fact )
But I would rather use a shield , If there was a example on how this could be replicated with this shield I think a lot more people (including me ) would be interested ,we all have remotes .so capturing the signal then microniseing the transmitter quite use full .

Just saying
