So i just bought a new laptop for college but up til' now i was always using computers in college. im trying to upload a sketch to the board and it says

Arduino: 1.6.6 (Windows 10), Board: "Arduino/Genuino Uno"

Sketch uses 3,448 bytes (10%) of program storage space. Maximum is 32,256 bytes.
Global variables use 240 bytes (11%) of dynamic memory, leaving 1,808 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.
Board at COM1 is not available
Board at COM1 is not available

  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.


Have you looked in 'Device Manager' to see which port the Arduino is actually using?
Then set that port number in the IDE.
Please do not PM me for help. I am not a personal consultant.
And others will benefit as well if you post your question publicly on the forums.


Have you try to restart a pc?
In some cases this procedure fix the problem.
Good evening!
