I am trying to turn an arduino UNO R3 into a keyboard. I have done this before with the R2, but I can not get it to work for the R3.
Is there somebody who has done this before, and who could give a clear guide on how to do this? I think it would help a lot of people since I found a bunch of questions about this on different forums, but no real answers..
This is project guidance, right?
Can you be a bit clearer? You mean a virtual USB keyboard? Or do you envisage a hacksaw, lots of buttons, etc?
... but I can not get it to work for the R3.
In what way did it fail?

Since there is only a minor difference between the R2 and R3, I suspect this may be a dubious claim.
I want to make the arduino be recognized by my (windows) computer as a HID device (such as a keyboard). The trouble is that the R2 uses an Atmega 8u2 chip whereas the R3 uses a 16u2 chip. And with the R2 you can make the arduino go in DFU mode by shorting the reset of the 8u2 chip to the ground and then flash its memory with another .hex file. But I can not get the 16u2 to go into DFU mode with the same trick..
Well that's a lot more detail than you provided in your first post.
yes, but is there anyone who has an answer to this problem?
