Wire coil detects the metal, buzzer beeps and distance of metal displayed on the screen. • Completely based and Arduino and components such as Ultrasonic sensor, buzzer, wire coil.

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.

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. An Arduino ...

[Mircemk] has an example that bends both worlds, with a single transistor oscillator and an Arduino. This type of metal detector has a large search coil which forms part of the tuned circuit in an ...

The hardware used in this research investigates the implementation of a pulse sensor utilising the Arduino development platform and an infrared sensor module created for the Arduino development board.
