Hi Every one
Hope you guys are fine.
I was using Arduino Nano v3.0 and it was working perfectly fine.
I programmed it and used it in my small project.
My windows 10 was auto updated and now cant see port in ARDUINO IDE.
I got Arduino Mega and it is perfectly working.
While uploading Arduino Nano v3.0 i get following error message:
"Arduino: 1.6.13 (Windows 10), Board: “Arduino Duemilanove or Diecimila, ATmega328”
Sketch uses 1,150 bytes (3%) of program storage space. Maximum is 30,720 bytes.
Global variables use 13 bytes (0%) of dynamic memory, leaving 2,035 bytes for local variables. Maximum is 2,048 bytes.
avrdude: ser_open(): can’t open device “\.\COM3”: The system cannot find the file specified.
Does it show up in the Device Manager? What does it show?
What serial adapter does it use? (check the markings on the chip near the USB port)
If it uses a CH340G, try reinstalling the CH340G driver (this is not included with the IDE, since only unofficial boards have used that USB serial adapter).
If it uses an FT232R, and was produced last year or so, it may have a counterfeit FT232R. A lot of arduino clones from china had the fakes, and FTDI updated the drivers so they are not compatible (and these new drivers get distributed through windows update). Google ftdigate for details if this applies to you.
You should be able to power a nano with 9v on the Vin pin, no problem (note that letting 9v onto any other pin will damage the board)
