You should post code by using code-tags
Hi Ikaterot,

welcome to the forum.
To get the best out of this forum you should take time to read this

You should post code as a code-section:

There is an automatic function for doing this in the Arduino-IDE
just three steps

  1. press Ctrl-T for autoformatting your code
  2. do a rightclick with the mouse and choose "copy for forum"
  3. paste clipboard into write-window of a posting

For doing this you should edit your first post through using the pencil-icon below your posting.

best regards Stefan
