Description

Welcome to the Techatronic, in this article we will share with you How to make a metal Detector with the Arduino. Arduino is the basic controller board that is using widely in the area of basic-level projects. so this project I am making also on the same. A metal detector is an interesting and important project. which can be used in many placed like Metal waste segregator, and finding metal from the ground, and many other places. I use the Arduino metal detector to find out the metal from my garden so that I will never hurt with that small pieces of metal. this metal detector is very easy and simple to make. you only need a small electronic circuit and have to embed this circuit with the Arduino board. So, let Talk about the working of the Arduino metal detector
