Arduino "Port" option grayed out

Question

My Arduino Kerfuffel

I just got an Arduino Nano, and I decided to first start off with a blinking LED. I did the wiring, I wrote the code, and I was ready to upload it. Verifying it was fine, but when I hit upload, it blurt out an error that read:

Serial port not selected.

So I looked it up, and turns out I have to go to Tools and select the port connected in Port. So I saw, but Port was grayed out. I looked everywhere in forums, but none of it helped.

One of the problems listed was that my Arduino was burnt out, but it still detected it as a device on Windows.

So what's happening?

More info:

Am I using a clone? Yes, I'm using a Keyestudio Nano.
What operating system are you using? I am using Windows 10

I used to run into this problem myself.

Your board is not being detected because it is a clone. However, I looked up your clone and it uses the ch340 USB-to-serial port chip.

To solve this, you simply need to install a driver so that your computer can communicate with your board. Just follow the instructions from the following link, and your board should appear! https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all#windows-710

Best of luck and let me know if you encounter any more problems!

PS: The link also has a video tutorial if you want to avoid reading.

Thanks! That fixed it. – jort57 Dec 04 '20 at 17:53
I'm running into another problem. Everything works, and I selected a port, but when I upload, it stays orange and never seems to upload. The bar freezes, and nothing happens. What's happening? – jort57 Dec 04 '20 at 19:20
Did you select the correct board? That is Tools > Board > Arduino Nano. Also just try to run the blink sketch for now so we can target the source of the error more easily – Thomas Michael Plantin Dec 04 '20 at 21:04
Yes, I did select it. – jort57 Dec 04 '20 at 21:38
Can you post a screenshot of what the Arduino IDE is showing? And also, does your code compile? – Thomas Michael Plantin Dec 04 '20 at 21:47
My code does compile. How do I post an image? – jort57 Dec 04 '20 at 22:23
What is the error message you get? Is it a countdown to 10 with avrdude? – Thomas Michael Plantin Dec 04 '20 at 22:52
It does not have an error message. It simply just freezes when it uploads. – jort57 Dec 04 '20 at 23:27
Does anything like this come up? Overriding Baud Rate : 115200 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x57 – Thomas Michael Plantin Dec 05 '20 at 19:04
What options do you have when you go to Tools > Processor? Try all of the different ones and see if that helps – Thomas Michael Plantin Dec 05 '20 at 19:06
Wait nevermind I fixed the problem by changing to the old bootloader. Thanks got your help, though! – jort57 Dec 06 '20 at 20:42
