Code to control an LED connected to pin 8 of the Arduino Uno based on input from a PIR motion sensor connected to pin 9. The LED turns on when motion is detected (HIGH signal) and turns off when no ...

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 ...

Arduino Mini Projects This repository contains two Arduino-based electronics projects developed for Smart Method training: Latching Power Switch Using Arduino Motion Sensor LED with Arduino 🔹 Project ...

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 your ...
