Hi @afridy

Did you select a port from the Tools > Port menu in Arduino IDE?

I'm not sure I understood correctly what you mean by this. Do you see a serial port for your board in the Windows "Device Manager"?

Yes, select port from Tools>port
but now working

yes ....
then select that port from tools>port
but still not working

It will not be possible for us to help you with that problem based on such a vague description. Please provide a detailed explanation of what you mean by this, including:

  • What did you do?
  • What were the results you expected from doing that thing?
  • What were the results you observed that did not match your expectations?
    • Make sure to include the full and exact text of any error or warning message you might have encountered.

If that means that windows does not see your boards, they will also not be available in the IDE.

If that is the case, is there a common denominator? Cable? TTL-to-USB converter?

Did it work before?

Which port did you choose? Does it disappear when you disconnect? If not, the port that you use is not the Arduino.

Are these boards you selected to try with the board you have, or are different boards you have that you tried communicating with? What board exactly do you have?

I also had a problem with the upload to the Arduino Uno board, in my case it was a USB port on the front of the case, I changed it to a USB port on the back and it's working fine, it's just a suggestion, I hope I could help, good luck.
