How to add rotary encoder for switching between radio stations?

[bertron]

Yes, that's more or less what I had in mind. I want to add a OLED display later, like that one described here:

But without the need to access from other devices to select the station. OK, I will have a look at the FAQ and tutorials.
Thanks!
