I don't know if it is still readable.

I took this sketch from the internet.

  • press the left button (verify) > is OK
  • press middle button (compile) > is OK
  • press tools in bar and select Serial Monitor
  • at Serial Monitor see different data ???
  • after pressing the Serial Monitor button (top right) the image follows as shown in the picture.

Hi @tombart. There is an important thing missing from your sketch. You must add a Serial.begin call to your setup function.

You can learn about Serial.begin from its Arduino Language Reference page:

This tutorial also demonstrates sending data from the Arduino board using Serial:

Please study those and see if you can solve your problem based on this information. After that, if you still have any questions or problems, let us know and we'll help you.
