This project demonstrates a simple motion detection alarm system using a PIR sensor, an LED, and a buzzer. When motion is detected, the LED and buzzer are activated for 2 seconds to indicate movement.

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 ...

This project demonstrates a proof-of-concept (PoC) test of a PIR (Passive Infrared) motion detector interfaced with an ESP32 and a 16x2 I2C LCD. The system detects movement and displays the motion ...

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...
