And, of course, with an Arduino and some know-how it’s possible to build a metal detector that has every feature you could want from even a commercial offering.

Connect the leftmost pin of the detector to Arduino Digital pin 2, the middle pin to Ground, and the rightmost pin to +3.3V. 3. Plug in the 2N3904 NPN transistor. Make sure the flat side is facing ...

Using the power of Arduino, Evan Kale has ingeniously transformed a weed wacker into an Arduino-powered metal detector. This innovative project showcases the versatility and potential of Arduino ...

Professional metal detectors are simple, but require a bit of work to make. But you can build a pared-down handheld detector using a calculator, an AM/FM radio and some masking tape.

With this simple project, which requires only about $40 and one hour, you could build your own EMI detector and start using it to save on your energy bills.

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 ...

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 ...

An Arduino may be one of the current go-to parts, but will it ever displace the 555? Perhaps not in the world of metal detectors!

An Arduino-based lie detector that can measure the skin's response to a question? This one certainly caught my eye.

Fruit Detector Last Updated: 7/24/18 Teaching Standards: This is an Arduino project called Fruit Detector. The idea behind the project is pretty basic. Different fruits have different resistances. The ...
