It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

We’re still not sure exactly how [connornishijima]’s motion detector works, though many readers offered plausible explanations in the comments the last time we covered it. It works well enough, though ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

The DIY arduino powered lie detector project is a straightforward application of the arduino board analog pins. It features a galvanic skin response measurements in a compact device setup. This ...

If you were wondering what happened to the Arduino Yun after it missed its original June release target, you can relax: it's now on sale worldwide. As promised, the $69 (€52) design combines a garden ...
