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 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 ...

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 ...

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 ...

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 ...

The Arduino generates a series of pulses on which are sent to the coil. These pulses create a magnetic field around the coil. When a metal object is brought near the coil, the inductance of the coil ...
