Since this is *your* project, you need to post your ideas and describe the difficulties you're encountering.

Since this is a school project, you need to do most of the work. Members are only allowed to try to guide you.

I don't know what Level 3 means, but this is a rather simple project. Been done many many times and chips are available to do it. The fact that you asked here before doing any research reflects poorly on you.

Ask yourself one question; how do I convert air vibrations ( which is sound) into an electrical signal?
It's up to you to solve that.
Use your books and internet.
