Show your code in code brackets and a circuit diagram of all connections including programmer used....NOT fritzing.

can you use the Arduino IDE and select the Tools->Port tab with and without your Arduino plugged in. The correct COM port should appear only when the Arduino is connected

The correct comm always appears its just when i click upload it says cannot access device

[gcjr]

sure you specified the correct board
Tools->Board

@gort1

avrdude: ser_open(): can't open device ".\COM6": Access is denied.

The correct comm always appears its just when i click upload it says cannot access device

What Arduino are you using?
What computer operating system are you using?

Is the Serial monitor closed when trying to upload?

access denied can be a a USB computer problem where something is blocking the port.

There is a tool called Process Explorer to see what that might be.

If your issue was not an open serial monitor and you need to use the process explorer tool, here are some links on how to use it.

Find and stop process blocking a port

I can't upload anything on pro micro

Microsoft provides a free tool named Process Explorer that can be used to identify the process that is using the port and causing the upload error. The next time you encounter the "Access denied" error, try this: Click the following link to open the documentation page for Process Explorer in your web browser: https://learn.microsoft.com/sysinternals/downloads/process-explorer Click the "Download Process Explorer" link on that page. Wait for the download to finish. Extract the downloaded file. …

I'm using arduino nano and im on windows 11 no its opened when i upload ill try using the process explorer and see if anything is blocking the port.

[gort1]

I used process explorer it said 0 searches found i went to device manager got the value put it in and there was nothing that was conflicting or blocking.

[gort1]

Yes i am using the right board it Says arduino nano under tool>board

[gort1]

Im not sure if this means anything but when i go to process explorer Arduino says access denied where it says path

[cattledog]

@gort1

Says arduino nano under tool>board

Which bootloader?

I think there maybe some driver issues with the usb interface chip (CH340?)on the Nano and Windows 11.

Try the forum search bar and then Google to get you started.

[gort1]

I'm using ATmega328P I've tried both this one and the old one and it didn't make a difference

[gort1]

Bro thank you so much you helped me figure out the issue. it was a problem with my drivers i just uninstalled and reinstalled and it worked.

[cattledog]

it was a problem with my drivers

Can you be more specific? I'm about to get a Windows 11 computer and I'm expecting my Arduino environment to be somewhat stormy.

[gort1]

The CH340 drivers were outdated and also their were duplicates so all i did was go to this website https://www.wch.cn/downloads/CH341SER_EXE.html when you download it it says uninstall and install i clicked uninstall then i installed the driver and it worked. I'm not sure if the issue was because there were duplicates of the same driver or because the drivers were outdated
