I am new to this, I have an Uno and I love it and works great. I just purchased a few Arduino Nano's and I was wondering how to upload a sketch. I am running Windows 10 just fyi.
I tried uploading a sketch and got the following error:
"vrdude: ser_open(): can't open device "\.\COM3": The system cannot find the file specified."
Also when I plug the Nano in I get nothing under the tools>ports in the Arduino software.
What can I do to fix this issue?
I have an Adafruit Trinket that is giving me the same problem even though I have the drivers. When I plug the Trinket in my computer doesn't recognize it at all and I get nothing under tools>ports in the Arduino software.
The Adafruit Trinket works differently from standard Arduino boards. It won't cause a port to appear, that's normal. You just need to select Tools > Programmer > USBtinyISP and then upload. For more information see:
While uploading the code, try to remove the Vin connection and then upload.
Once uploading the code is done, then connect the Vin and check the working.

Your first step should be to check Windows Device manager. It might show under other devices which would indicate that you need a driver (see pert's reply above).
