A basic coil-and-oscillator circuit that changes pitch near metal objects.

Description

A basic coil-and-oscillator circuit that changes pitch near metal objects. This is a school-level project designed to be safely built and clearly explained by the student presenting it, using components that don't require advanced lab equipment.

Objectives

Build a working metal detector using a simple coil circuit and be able to explain how each component contributes to its function.
