Hello. I'm just starting out on using Arduinos. I have an Arduino Nano but I can't seem to communicate with it. I've tried it with two computers. On one, the Port under Tools is greyed out. I've tried fixing this but the instructions on how to fix this don't match the options I see on the screen. On my other computer, I get a programmer is not responding error. Can anyone tell me how to fix this problem?
Regards, Stuart
If the port option is greyed your port and cable are not really working. Try connecting the cable to another USB port on your system.
I've managed, somehow, to get the port to not be greyed out, but I get the same error now as I get on the other computer.
Correction, the error is not the same, it is stk500_getsync() attempt 9 of 10: not in sync: resp=0x00 .
I now get the same not in sync error on both computers.
Try new nano and check same problem occurs or not
Have you tried the various options under tools -> processor in the IDE?
Your post is lacking details:
Which OS?
What does your OS think about the board? In Windows that would be: what happens in device manager when you connect the board?
Which version of the IDE?
To answer your questions: Windows 10 on both computers. On both computers, the device is acknowledged when plugged it. On the desk top, in Device Manager, "Other devices" appears with "USB serial" under it. This has the yellow "!" symbol. Looking further into it, it says that there is no driver installed. I've tried installing drivers, but the system doesn't recognise them as drivers.
When I plug it into the laptop, it acknowledges the device, and "Ports" appears in Device Manager. Under that is "USB-SERIAL CH340 (COM4)" Under that, it reports that the device is working properly. When I try and upload, I get the not in sync error. With the desktop, I get the further error of "programmer not responding". I've tried two Nanos, and neither of them work.
The IDEs are 1.8.10 on the desk top, 1.8.13 on the lap top.
My first step would be to load one of the LED blink examples and verify the board and programming is working.
That's what I have tried to do, with both computers.
I order to gather more information that might help us to troubleshoot your problem, I'm going to ask you to post the full output from the laptop when you upload in verbose mode.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with

option enabled in File -> Preferences.
Here is the output from the desktop computer.
Select Tools > Processor > ATmega328P (Old Bootloader) from the Arduino IDE's menus and then try uploading again.

With old bootloader.
Select Tools > Port > COM4 from the Arduino IDE's menus and try uploading again.
COM1 is the only option.
Is COM4 still shown in Windows Device Manager?
Only COM1 appears.
Do you have any idea about why it appeared before and it doesn't appear now?
