Metal Detector is a security device which is used for detecting metals which can be harmful, at various places like Airports, shopping malls, cinemas, etc. Previously we have made a very simple Metal ...

The same holds true for a lot of microcontroller designs including [rgco’s] clever metal detector that uses very little other than an Arduino. The principle of operation is simple.

This repository contains the Arduino code, configuration, and assembly instructions for building a simple vibration/earthquake detector using an accelerometer sensor. The system is designed to detect ...

This one differs by using an Arduino to read from the metal detecting coil. The circuit starts with an oscillator that produces a signal of about 160 kHz which is constantly measured by the Arduino.

This project involves building a simple metal detector using an Arduino microcontroller. The metal detector works by detecting changes in the electromagnetic field caused by the presence of metal ...

One of the essential parts of any home security system is a door detector that lets you know when a door opens. Over on Adafruit, they show you how to build your own that hooks into IFTTT so you ...

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 ...

It’s very simple to implement a valid metal detector with good performances. Very often people lose their metal objects at the beach or in the countryside. Coins, rings and necklaces disappear when ...

Metal detectors are used for the safety of people to detect anyone carrying a metal (Arms etc). In this project we are going to design a simple metal detector circuit.
