Arduino Metal Detector : 6 Steps (with Pictures)

The heart of the detector is the Arduino Nano Atmega328 which is used to measure the pulse width of a signal which passes through each search coil. The Arduino produces a square wave pulse which is fed into an LC Tank circuit which produces a decaying sine wave signal at a frequency determined by the resonant frequency of L & C.

Detector (radio) - Wikipedia

In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. The term dates from the first three decades of radio (1888-1918). Unlike modern radio stations which transmit sound (an audio signal) on an uninterrupted carrier wave, early radio stations transmitted information by radiotelegraphy.
