Motion Detector Learning Book 📘 Motion Detector EN HI 1. Introduction 🌟 This project is a Motion Detector using Arduino. It detects movement using a PIR sensor and gives alert using LED and buzzer. It is useful in security systems. Ye Arduino ka Motion Detector project hai. Ye PIR sensor se movement detect karta hai aur LED 💡 aur buzzer 🔔 se alert deta hai. Ye security ke liye useful hai. 2. Components 🧠 Arduino: Controls the whole project PIR Sensor: Detects motion LED: Shows light signal Buzzer: Produces sound Resistor: Controls current Ohm: Unit of resistance Arduino: Project ko control karta hai PIR Sensor: Movement detect karta hai LED: Light deti hai Buzzer: Awaaz karta hai Resistor: Current control karta hai Ohm: Resistance ki unit 3. Connections 🔌 PIR → 5V, GND, D2 LED → D7 + Resistor → GND Buzzer → D10 → GND PIR → 5V, GND, D2 LED → D7 + Resistor → GND Buzzer → D10 → GND 4...
