I have an issue : I put 16V by accident on my arduino uno board and since, it is not recognize anymore by my computer.
I guess it is because of the 16V thing but maybe I am wrong?
Is there any chance it is something else? How could I check?
Is it possible that just the atmega328 has died?
I checked on electronic shop nearby and they have atmega328-au, atmega328p-au, atmega328p-mu. What the difference? wich one will work on Uno?
