It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Basic motion sensing setup using Arduino, PIR sensor, LEDs, and push button for interaction & Motion-triggered alarm system with Arduino, PIR sensor, piezo buzzer, and LED alert. // first pic This ...

An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion detection using an HC-SR04 ultrasonic sensor, and ...

We’re still not sure exactly how [connornishijima]’s motion detector works, though many readers offered plausible explanations in the comments the last time we covered it. It works well enough, though ...

If you searching for an LED matrix for your next project or to add to an existing application you may be interested to know that the Maker LED Display is now available to purchase from the Crowd ...
