Metal-Detector-Circuit-using-Arduino The Arduino generates a series of pulses on which are sent to the coil. These pulses create a magnetic field around the coil. When a metal object is brought near ...

There are two separate detector coils wound around a ferrite rod that made up the metal detector. It has the ability to detect metal as well as live electric cable since the circuit is a beat ...

Robot/metal detector circuit diagram. Source: Interesting Engineering Build the PCB as shown, with the components required. Then insert the Arduino RF Nano, and the DC Motor Driver onto the board.

An Arduino can measure time, a coil and a resistor will create a delay proportional to the circuit values, and metal around the coil will change the coil’s inductance.

Detects a small metal coin at a distance of 4-5 cm, and larger metal objects at a distance of 10 cm and more. In fact, its purpose is to locate more accurately the object that was previously detected ...

[Mircemk] has an example that bends both worlds, with a single transistor oscillator and an Arduino. This type of metal detector has a large search coil which forms part of the tuned circuit in an ...

4. LEDs: For the celebratory light show. 5. Power Source: To power the entire setup. The construction process involves assembling the Colpitts Oscillator circuit and connecting it to the Arduino.
