Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion ... using a microcontroller is probably overkill for most motion detector safety light circuits because ...

The ICU-Duino motion sensor Arduino Shield has been designed ... which means that you can control your Arduino circuit wirelessly from further than five meters away! The ICU-Duino connects ...

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 ...

There are loads of unique sensors available on the market for Arduino boards ... PIR motion sensors use infrared light to detect movement. Light is emitted and the sensor will trigger if it ...

Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your desk or into a room. It’s completely open source and the notifications system runs on ...

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 ...

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 ...
