Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

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.

The tiny microcontroller brain To be frank, using a microcontroller is probably overkill for most motion detector safety light circuits because the PIR sensor module itself can handle the task ...

Outdoor light motion sensors can add a healthy level of security to your home. Here's how to set them up.

The (r)evolution Arduino motion sensors have been specifically built for projects that require the addition of self tracking applications based on information from your body.

This is a firmware application written in C++ using Arduino and Adafruit libraries. It sleeps in low power mode until, activated by the motion sensor, it takes a picture.

All you need is an Arduino, a motion sensor, a few wires and headers, and the code provided at the site below. Hit the link to see step-by-step instructions on how to put it together.

Historically, we’ve used IR and ultrasonic sensors but [Makers Mashup] decided to use an ESP32-Cam as a motion sensor in his latest animatronic creation.

The Philips Hue line of lights have been controllable via an indoor motion sensor for some time, but Signify is today introducing an Outdoor Motion ...

For instance, you could use an Arduino to build a motion-controlled video camera or to remote control the lights in your sitting room.
