Sketch uses 928 bytes (2%) of program storage space. Maximum is 32,256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes. 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" option enabled in File -> Preferences.

It is unlikely that your board is on COM1.

Check your device manager for the correct one and select that in the IDE.
