The Arduino Mega interfaces with a metal detector module to detect the presence of metal objects using electromagnetic induction, suitable for security systems, treasure hunting, and industrial ...

Arduino ADC is usable around 10/12 bits. That means it can measure up to 1024/4096 diferent voltage levels. Counting frequency instead can let you choose your own diferent measurement levels ...

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.

A new Instructables page has been created to make an eco-friendly DIY metal detector using an Arduino Mega just been combined with a 3.2 inch TFT LCD ...

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 ...

Next, grab the metal detector module. Wire up and solder as instructed. Secure the metal detector module to its relevant 3D printed mounting, as well as, the positioning arm.
