Need some help with a project

Hey all! New to this place but I have a basic understanding of circuits.

I have an idea for a project I want to do but don't quite know what I need.

What I would like to do is a circuit that counts the number of times something like a lid is opened and when that number reaches about 10-15 have a small buzzer/alarm go off until a reset button is pressed.

Any help is greatly appreciated

Thanks all!
