How To Make a Metal Detector Circuit

Introduction

In this Article and video the students of electronics will learn how to make a Metal Detector Circuit. It is a easy electronics DIY project which you can easily make at home. It is metal detector without IC. We will use transistor for making this powerful metal detector. This circuit is very useful to detect any metal. In this circuit using BC 547 transistor and some supporting components. I will show you the complete process of making Metal Detector Circuit step by step.
