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 ...

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 ...

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 ...

If you’ve always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your ...

Makers, developers and hobbyists looking to at the ability to monitor motion, direction and orientation to the next Arduino project may be interested in a new breakout board offering an all-in-one 9 ...

Inspired by the recent launch of the series “Alien: Earth”electronics enthusiast Rob Smith has created a “fully working M314 motion detector”. The project remained in the drawing boards for a long ...
