DIY Super Simple Sensitive Metal Detector

Setting up the Metal Detector is very simple: - First we need to place the two windings so that the gap between them is the smallest and the variable capacitor is in the middle position. - A very high frequency tone is now heard on the handset. - Next we need to gradually increase the overlap, reducing the frequency of the sound in the handset.

Arduino Metal Detector : 4 Steps

Step 2: Circuit Diagram. We have used an Arduino Nano for controlling whole this Metal Detector Project. A LED and Buzzer are used as metal detection indicator. A Coil and capacitor is used for detection of metals. A signal diode is also used for reduce the voltage. And a resistor for limiting the current to the Arduino pin.
