Yesterday I came back home and pluged in the Arduino Nano (not 3.0), but windows 7 said that my dispositive were not regognized. One day before that, i uploaded many codes, and he was working fine, but now he doesen't connect to my pc.
The last program that I uploaded is working fine in arduino, but i can't comunicate with PC by serial, and the PC doesen't recognize the Arduino.
What I have done:
- Manualy downloaded drivers
- Tried to connect in another pc
- Tried to download bootloader
Can anyone help me?
