Please don't hijack threads @trkifathi2024. I have split your post out to its own topic.

Hijacking is against the Arduino forum rules. The reason is that it may sidetrack the discussion, even preventing the creator of the topic from getting the assistance they need. It also reduces your own chances of getting assistance.

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.

Re-format your code when you post it to the forum.

  1. Copy your code.
  2. Open your IDE.
  3. Paste your code in the IDE
  4. Press CTRL-T to format your code.
  5. Press CTRL-A in your IDE to select all your code.
  6. Open your message.
  7. Select your unformatted code in your message.
  8. Press DELETE.
  9. Click the < CODE > button in your message box
  10. Where you see ```type or paste code here```...
  11. Select those words, then...
  12. Press CTRL-V to paste your formatted code.

You should see this:
