In this article arduino metal detector circuit is composed with proximity detector ic cs209a.
Metal detector using arduino february 21 2014 by ajish alfred metal detector is a device used to detect the presence of a metal in its proximity without touching it.
The arduino based metal detector explained in this project is basically a frequency meter which measures the resonating frequency or time period of a tank circuit.
For this metal detector project we will be using an arduino to process the oscillation signal instead of offsetting the oscillation with a second tank circuit.
The arduino produces a square wave pulse which is fed into an lc tank circuit which produces a decaying sine wave signal at a frequency determined by the resonant frequency of l c.
