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 ...

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.

There are other metal detector projects using AVR and PIC. This one is nice and simple. I do wonder why the 7.64khz frequency was chosen instead of something in the 15k to 20k range wasn’t used.
