TechKiwiGadgets explains more about the inspiration behind the Arduino DIY metal detector and the technology ... and once an object is located, the four sensors can be shown in a split-screen.

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 ...

Evan Kale has ingeniously transformed a weed wacker into an Arduino-powered metal detector. This innovative project showcases the versatility and potential of Arduino in creating practical and fun ...

The digital signal output to be detected (usually marked as DO in the module) is applied to D2 input of the Arduino. Analog output (marked as AO) from the module is not used here. Sensor-head of the ...

The “snooper” here is an ordinary passive infrared (PIR) motion detector module ... regulator, and Arduino IDE compatibility. The code is an Arduino project for the Digispark Attiny85 to turn on a ...

the detector would trigger off its own LEDs and buzzer, trapping itself in a never-ending loop. [Mirko] solved this by encasing the Arduino inside a closed, grounded metal box with only the ...
