Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1) ...

We have a collection of almost 500+ Arduino projects with Code, Circuit diagrams, and detailed explanations, completely free for everyone to build and learn on their own. Quick Start: IR Sensor With ...

This repository demonstrates how to implement motion detection using a PIR sensor with an LED and serial output across multiple platforms like Arduino Uno, ESP32, Raspberry Pi Pico, and STM32 Nucleo.

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.
