This voltage can be read by an Arduino digital input and then the Arduino can act upon it. The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack. The one on the right comes ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion ... and Arduino IDE compatibility. The code is an Arduino project for the Digispark Attiny85 to turn on ...

In the microcontroller era today, Arduino is more than just ... (H)” level input to wake up. The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor ...

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 ...

[IngGaro]’s latest project uses the full range of features available in this versatile microcontroller and has turned an Arduino Mega into a fully-functional home alarm system. The alarm ...

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada.

The first trick, shown in the video above, is an Arduino-powered squirt bottle that also uses a motion detector to fire rapidly every time there's some motion in front of it. If you're trying to ...
