Using motion detectors and an Arduino you can trigger lights ... A simple way to think of the sensor is a switch; the diagram below explains the difference between the two approaches.

Using the Arduino Sketch [Eric] has written, you can easily plug in your Wi-Fi information and IFTTT key and trigger. All that’s left to do is put this IoT motion sensor to work by mounting it ...

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. Images are posted to ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go. If that sounds ...

Unfortunately, real-motion detection requires rather more sophisticated and thus more expensive sensor. However ... is usually done with the help of a microcontroller. HB100 outline diagram and ...

You'll definitely need some gear for it—the Arduino for one, but also a PIR motion sensor, not to mention the (cleaned and rinsed!) Raid Power Sprayer motorized spray bottle. The second trick is ...
