Here in this circuit, we have used a coil having around 20 turns or winding with a 10cm diameter. We have used an empty tape roll and wind the wire around it to make the coil. 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.
Mar 11, 2011· The detector works based on the resonant frequency that has been set change when there is a metal object is located quite close to the search coil sensors. Tuning circuit (tuned circuit) should be a part of our oscillator circuit so that if approached by a metal coil sensor specific hence the output frequency of the oscillation circuit is about to change.

Cheap Metal Detector The idea of this circuit is to hack PIC oscillator circuit, by replacing the crystal by a coil : the frequency of the oscillator then depends on presence of metal near the coil, just like in a classic metal detector. __ Designed by Bruno Gavand
Jan 16, 2018· Lie Detector Circuit in Action: Once you have assembled your board it's time to have some fun. Just power it on with a 9V battery and you should see the green LED going high. If you short the two yellow wires the green LED should turn on and the red should turn on. If so then it means everything is working as expected.
