| May 13, 2021 at 14:18 | comment | added | user1700890 | Thank you, All! Indeed, it looks like I need to install CH340 USB driver on my Windows 10. I tried my Arduino with Ubuntu and it worked almost perfectly. Too bad Windows comes without this driver. | |
| May 6, 2021 at 13:14 | comment | added | PMF | @user1700890 If the port is visible in device manager, it is shown there. You should see something like "USB Serial CH340 (COM4)". | |
| May 6, 2021 at 13:03 | comment | added | user1700890 | @Juraj Thank you, but how can I install it on Uno if I cannot connect it to computer? | |
| May 6, 2021 at 13:02 | comment | added | user1700890 | @PMF How can I tell it which port to use? | |

I never used the Web IDE, but can you find a "Serial port" setting anywhere? The message Serial port not selected indicates that it does not know which port to use. Since you could have connected more than one Arduino, you have to tell it which serial port it should use (typically COM3 or COM4)

In device manager I see USB serial with exclamation mark ... what does the exclamation mark mean?
