“Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical and digital world.
In this Instructable, we are going to make a Metal Detector. PS : This is not intended for total beginners.
A metal detector is an electronic instrument which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground.
But the metal detector we are going to make won`t be useful in actual cases, Its just for fun and learning.”
