Hi, I'm new to Arduino and want to start playing with a position encoder project. I want to read 2 rotational encoders (digital intfc) and transmit position info via Bluetooth. I want it to be compact. I will probably use breadboard space to add a Blutooth transceiver (choice is TBD). Anyway, I find it hard to compare the different Arduino boards. Is there a comparison table? What would you recommend? I'm thinking maybe the Uno or Nano.
