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 ...

Arduino’s open-source platform makes it easy for makers, students, and hobbyists to build powerful multi-sensor projects for home automation, monitoring, and IoT applications. From motion and gas ...

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 ...

Recent Arduino projects showcase increasingly sophisticated multi-sensor integration, from multiplexers solving I²C address conflicts to interactive hubs with multiple modes. Developers are pairing ...

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 ...
