Build Your Own Metal Detector with an Arduino

The inductor of the above tank circuit forms the detector of the metal detector (a large coil of wire). When metallic material approaches the center of the inductor (the detector coil), it enters the magnetic field created by the inductor. This changes the magnetic permeability of the inductor's core, causing the inductance to change. The ...
