Design And Construction Of A 20-m Distance Remotely Controlled Metal Detector Using Arduino

   AbstractThe project DESIGN AND CONSTRUCTION OF A 20-METRE DISTANCE REMOTELY CONTROLLED METAL DETECTOR is used for detecting metallic objects such as phones, bombs, and other metallic objects that are hidden from view. The design is based on the principle of the Resonant Frequency Oscillator (RFO) metal detectors in which oscillation is a function of parallel connection of an inductor and a capacitor operating in resonance. The project is divided into two sections. The transmitter section acts as a remote control. This section has push buttons and uses…
