I have this message coming up when uploading to the Arduino Uno
Arduino: 1.8.2 (Windows 10), Board: "Arduino/Genuino Uno"
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.
dose anyone know how to fix this by any chance and help would be thankful
Select the port corresponding to your Arduino from the Tools -> Port menu. windows will assign new port numbers if you plug it into a different port.
If that menu is greyed out, that means you don't have drivers for the Arduino installed, or there's a hardware problem. If you're using a clone arduino instead of an official one, it probably has a CH340G USB-serial adapter; the drivers for that are not included with the IDE - google will find you the CH340G drivers for your operating system.
when i chose the right port it worked thank you for the help
