Raspberry Pi HATs offer small, stackable data acquisition with features like analog and digital I/O.

Using motion detectors and an Arduino you can trigger lights ... LOW); delay(500); } } Here is the circuit for the Sparkfun Active Low style sensor. PIR Pin “+” connects to ...

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 ...

Arduino is able to interpret signals from a variety of sensors. By placing a unit equipped with an ADXL345, an accelerometer for detecting motion, or a Piezo sensor ... link the circuit to your ...

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 ...

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 ...
