  • Metal Detector using a 2 Pulse Induction Coil

    In a PI metal detector, the magnetic fields from target objects add their "echo" to the reflected pulse, making it last a fraction longer than it would without them. A sampling circuit in the metal detector is set to monitor the length of the reflected pulse. By comparing it to the expected length, the circuit can determine if another magnetic field has caused the reflected pulse to take

  • Build Your Own Metal Detector with an Arduino

    Metal Detection Circuit Schematics . I used an Arduino UNO to program a DIP ATMega328. I then removed the ATMega328 from the development board and embedded into a perfboard along with the rest of the circuit. The Colpitts oscillator, on the bottom left on the diagram, feeds the oscillation into counter 1 (pin T1) of the chip (marked as digital pin 5 on the Arduino UNO), where it constantly
