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 ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

A few years ago Josef Holmner created an awesome Arduino powered wrist worn quadcopter controller that allows pilots to control their flying drones using just one arm, and gestures which trigger ...

IFTTT, or "If This Then That", has undergone a major site overhaul. In addition to an updated graphic design, the rule-based automation website features new channels, Quick Triggers, and now supports ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino..

One of the essential parts of any home security system is a door detector that lets you know when a door opens. Over on Adafruit, they show you how to build your own that hooks into IFTTT so you can ...
