I'm going to ask you to post some additional information that might help us to identify the problem.
Please do this:
- When you encounter an error, you'll see a button on the right side of the orange bar in the Arduino IDE: Copy error messages. Click that button.
- Open a forum reply here by clicking the Reply button.
- Click the
</>icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
- Press Ctrl+V.
This will paste the compilation output into the code block. - Move the cursor outside of the code block markup before you add any additional text to your reply.
- Click the Reply button to post the output.
