TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The … ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

Hot glue the motion sensor to the hole you drilled for it. Feed the wires through their respective holes and attach them to the Arduino and the power relay. Reattach the enclosure’s top cover.

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

Anyone searching for an Arduino project to keep them busy this weekend may be interested in a new motion activated wildlife camera constructed using the Adafruit Feather M0 development board.
