A wonderful activity that gets you outside, explores new areas, and can even provide an exciting discovery is metal or gold detecting. Verify your local laws regarding what to do in the event of a discovery, especially with regard to potentially dangerous stuff, archaeological remains, or valuable items with emotional or economic value.
A metal detector is also a type of security tool used in a variety of locations, including shopping centers, movie theaters, airports, and so on, to find potentially dangerous metals. I am currently utilizing Arduino to develop the metal detector after previously creating a very basic one without a microcontroller.
The coil and capacitor I'll be using in this project are what will be used to identify metals. Here, I've built a metal detector project using an Arduino Uno. For everyone who enjoys electronics, this is a pretty intriguing project.
This detector quickly begins to beep if it senses the presence of metal nearby.
To construct a basic DIY metal detector with Arduino, you will need the following parts:
1-Arduino (Uno or Nano)
2-Coil 10-20m
3-100nF capacitor
4- Active Buzzer
5- 220-ohm resistor
6-LED
7-1N4007 diode
8-Breadboard or PCB
9- Connecting jumper wire
10- 9:12v Battery
- Arduino Uno Circuit
- Arduino Nano Circuit
