Chinese arduino uno clone doesn't work as it should

just bought an arduino from aliexpress link : https://www.aliexpress.com/item/1005006230509796.html
That arduino doesn't work with any code, even after connecting everything right (i checked) it still won't do anything, i am a newbie in this things and i use AI to generate code, in emulators (wokwi.com) it works fine but irl it just doesn't. I have got ch340 driver and still nothing, if someone knows how to make it work, please tell me.

Try removing all external hardware things connected to the Arduino, besides the USB cable.

Suggests hardware or driver problem.

How does the board show up in Device manager or similar?
Where did you install the CH340 driver from?

Please be more specific about the problem that you're encountering. E.g. can you upload code or not?

  1. Which operating system (Windows, Linux, Mac) are you using?
  2. Which version of the IDE are you using?
  3. Did you select the correct board?
  4. Did you select the correct port?
  5. Any error messages (see below)?

If you indeed have an upload problem, please disable verbose output during compilation and enable verbose output during upload under file/preferences in the IDE, upload the blink example and post the result here (using code tags as described in https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966#use-code-tags).

If you have a compilation error, please enable verbose output during compilation and set the Warning level to All, compile your sketch and post the results here (again using code tags).

Maybe you should start more simple than using code for your project. Check some of the examples in the IDE like blink; you can modify the delays so you have a visual indication that the sketch indeed works as expected.

1 I tried, blink without and with cables and button, no diffrence
2. i don't know what that means
3. In ports (COM or LPT) as USB-SERIAL CH340 (COM4)

I had the same problem maybe 1 year ago, that was the driver
I installed the CH341SER.exe version and resolved for me , maybe that will help you !

strange for one UNO board

Not behind a PC at the moment.

  1. There are three buttons near the left top. The right one will be frayed out, the left one is compile (verify) and the middle one fir upload. Which one do you click?
  2. Please follow the instructions for the upload problem that I gave earlier and post the results. There is a bug in IDE 2.3.3 that results in upload errors not being reported in the notification area in the right bottom.
