Hello there! Sorry if this is the wrong forum for this question, but I didn't quite find another subforum where I could ask this.

Anyways, I recently purchased an Arduino Uno R3 for a self project. I want to recreate this project I found online but I have a couple of questions since it's based off the Arduino Uno R2 SMD.

1. Is there a difference between programming an Arduino Uno R2 and an Arduino Uno R3?
2. Can the firmware used to reprogram the R2 into a HID USB keyboard be used on an R3?
3. And for future reference, can the R3 be reprogram to act as a USB mouse?

P.S. I was searching the forums for answers to my question, but I didn't find anything for a while. I'll keep searching but hopefully this will get me faster results.

No. The difference is in the support hardware for the 328 chip, not in the 328 chip itself.

Yes. The same chip is used on both boards.

Yes. Not that I understand why you want to do that.

Thanks for the answers! As for the mouse thing, there are some games where it only requires mouse input, so I though I could learn more by trying something a bit different. Anyways, thanks again!
