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.
