Дослідження конструкції та принципу роботи металошукача на базі Arduino

Abstract

This work is dedicated to the design and research work metal detector set up on the basis of Arduino. Its principle of operation is that the oscillating circuit, whose frequency depends on the inductance of the coil, Arduino monitors the frequency changes. There are static and dynamic modes. Static mode: by pressing the button, the current frequency is remembered, beeps when there is a deviation. Dynamic mode: the frequency is constantly striving for the current, responds only to the sudden appearance of metal.
