Once metal is placed near the inductor L1, it will trigger current production from the proximity detector IC, which in turn lights the LED. So to test this circuit, just place a metallic object near this inductor. When done, the LED should turn on. When the metallic object is moved away, the LED should shut off.

We will develop a basic metal detector circuit in this project. There are so many metal detector projects, but most of them are in the design complex so we will make a basic 555 Timer IC metal detector circuit. This circuit is easy to make and requires a few basic components. We must understand the idea of inductor and RLC circuits …
The output diode drops the output offset from ~200 mV to 0 mV. Another option is to use a CA3130, it has a slew rate between 10 and 30 v/us and a GBW of 15 MHz. For more gain (per stage), a more modern OpAmp such as the OPA365 is required: This OpAmp is rated at a GBW of 50 MHz and a slew of 25 v/uv:
The best option is to take the whole detector kit outside to test away from any RF or electrical interference, such as electrical wires or wireless routers. To permanently connect the coil to the circuit board, one can use a shielded USB 2 cable or RG6 coax (center contact to inside leads of the coil, outside leads of coil to cable shield).

As you start researching the hobby of metal detecting, you will quickly learn that there are two types of gold detectors to choose from. Those seeking gold can choose between VLF circuits with high sensitivity or Pulse Induction PI detector circuits, which use a pulse generator to create the signal in a series of pulses. As the reflected pulse ...
Detectors that are best suited for gold detection will operate at much higher frequencies, typically between 15kHZ – 61kHZ, whereas hobby metal detectors usually operate at lower frequencies between 6.5kHZ – 14kHZ. Gold detectors can operate on high frequencies and in challenging ground conditions by picking up gold even in small sizes.
Step 4: Setting Up and Using the Detector. If the detector is build properly and the program is written to the Arduino, the easiest (if not the only) way of setting the unit up is to use an OLED display. The display is attached to 5V, GND, A4, A5. The display should show „calibrating" after the unit is powered up.
