avrdude: ser_open(): can't open device "\.\COM3": The system cannot find the file specified.Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
I don't see a question.
