TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

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 combines a joystick, servo motor, ultrasonic sensor, two LEDs, and a buzzer to create an interactive object detection system. The joystick is used to rotate the servo motor left and right ...

ESP32-CAM Motion Detection & Notification System This project implements a motion-activated camera system using an ESP32-CAM module. When motion is detected via a PIR sensor, the ESP32-CAM captures a ...

If you've always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by ...
