How to Build a Metal Detector Circuit

In this project, we will demonstrate how to build a simple metal detector circuit. The device we then build will function as a metal detector that can scout out metal objects, such as coins, nails, keys such as car keys you may not be able to find, and even gold if you're looking for in a beach (though this one may not have industrial strength).
