There are other metal detector projects using AVR and PIC. This one is nice and simple. I do wonder why the 7.64khz frequency was chosen instead of something in the 15k to 20k range wasn’t used.

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 ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

One of my new obsessions is building metal detectors. BFO’s are great for “probes” (ie close range detector for searching the larger area scanned by your bigger detector).

Calibrate the sensors to ensure accurate readings. This involves setting baseline values for both the accelerometer (zero-point calibration) and soil moisture sensor (dry and wet calibration).

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 ...
