[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 ...

Raspberry Pi HATs offer small, stackable data acquisition with features like analog and digital I/O.

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 microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list. There are ...

[Sebastian Tomczak] was borrowing a homeade muon detector from his friend, and managed to hook it up to his computer through an Arduino. The detector itself uses 3 fluorescent tubes to detect ...

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...
