I just got a hold of an Arduino UNO R3, and when i tried to upload the code, this came up:
avrdude: ser_open(): can't open device "\.\COM1": 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"
enabled in File > Preferences.
I have changed the programmer and tried uploading using each programmer. The result was a fail. I have been looking on other websites with no results. I am using a sketch by sparkfun.
