[Dzl] starts his write up with an explanation of how most oscillator based metal detectors work. This one differs by using an Arduino to read from the metal detecting coil. The circuit starts with ...

Our old math teacher famously said, “You have to take what you know and use it find what ... [rgco’s] clever metal detector that uses very little other than an Arduino. The principle of ...

A new Instructables page has been created to make an eco-friendly DIY metal detector using an Arduino Mega just been combined with a 3.2 inch TFT LCD touchscreen to provide a fantastic readout ...

Robot/metal detector circuit diagram. Source: Interesting Engineering Build the PCB as shown, with the components required. Then insert the Arduino RF Nano, and the DC Motor Driver onto the board.

This piece made use of a number of different technologies and models, including the Arduino development board, GSM, GPS, a bomb/metal detector, driver circuits, an alarm with motors, and a robot model ...

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 ...
