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 ...

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 ...

This project builds a real-time stress detection system using a PPG sensor and Arduino UNO R4. Pulse data is processed in Python to extract features and predict stress with a Random Forest model.

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 ...
