In the previous article we covered [connor] demonstrating the motion detector. Something about the way the ADC circuit for the Arduino is wired up makes it work. The least likely theory so far ...

[Dzl] starts his write up with an explanation of how most oscillator based metal detectors work. This one differs by using an Arduino to read from the metal detecting coil. The circuit starts with ...

An Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a ...
