I started a new project and I keep getting the same error again&again

I moved your topic to an appropriate forum category @kunstmaan.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Hi @kunstmaan.

@kunstmaan

The wire lib doesnt start

It will not be possible for us to help you with that problem based on such a vague description. Please add a forum reply here that provides a detailed explanation of what you mean by this, including:

• What did you do?
• What were the results you expected from doing that thing?
• What were the results you observed that did not match your expectations?

Make sure to include the full and exact text of any error or warning messages you might have encountered.

wire.begin();

Wire.begin(); perhaps?

Hi,
What model Arduino are you programming to?

Thanks... Tom..
