Hello,
I contacted it to my computer windows and I tried basic code
And I got a message:

In your original topic on this same problem that you created less than an hour ago, you were asked to read How to get the best out of this forum and follow the advice to be found there.

You have not read that topic. There is a number that appears next to the link when the link is followed, and that number has not appeared - so you have not read the topic.

Had you done so, you would have known not to start up another topic and not to post code as a screenshot.

I have merged your cross-posts @rannaor .

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting can result in a suspension from the forum.

In the future, please only create one topic for each distinct subject matter. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Hi @rannaor. The output you shared is the output we would expect from a successful upload.

Did Arduino IDE indicate the upload failed? If the upload fails, you will see an "Upload error: ..." notification at the bottom right corner of the IDE window:

If the upload succeeds, you will see a "Done uploading." notification there:

Note that the success notification is hidden after a few seconds, so you might miss it if you aren't watching, but you can click the :bell: icon at the right side of the status bar to show the hidden notifications again.

If you didn't get an "Upload error: ..." notification then the upload was successful and you don't need to worry about this message.

Notes on the Coloration of Upload Output in Arduino IDE

You might notice some messages printed to the "Output" panel at the bottom of the Arduino IDE window in red text while uploading. The color might give the impression that these messages are intended to communicate some sort of a problem has occurred, but it is not so in this case.

The developers of the 3rd party tool Arduino IDE uses for uploading made an unusual decision to print even the tool's purely informational output to the "standard error" stream (AKA "stderr") instead of the more common practice of printing it on the "standard output" (AKA "stdout") stream. Because it is usually associated with errors or warnings, Arduino IDE colors all output received from the stderr stream red (at least when the default IDE theme is selected).

So don't be mislead by the color of the text during the upload (though you should pay attention to red text printed while compiling because the color is significant in that case). As long as you don't see an "Upload error: ..." notification, all is well with the upload.
