🚶‍♂️ PIR Motion Sensor with Arduino UNO | TinkerCad Simulation Tutorial 🚀

Описание: Welcome to BK TechRoots!
In this video from our TinkerCad Simulation Playlist, we’ll learn how to interface a PIR Motion Sensor with Arduino UNO and detect motion using the Serial Monitor in TinkerCad.

Instead of using an LED, we display the motion detection output directly on the Serial Monitor, which helps beginners clearly understand how the PIR sensor sends HIGH/LOW signals to Arduino.

📌 What you’ll learn in this video:
What is a PIR Motion Sensor and how it work? 🚶‍♂️
How PIR sensor detects human motion 🔍
Interfacing PIR sensor with Arduino UNO 🔌
Reading PIR output using Serial Monitor 🖥️
Complete circuit setup in TinkerCad 🧩
Simple and beginner-friendly Arduino code 💻

This project is perfect for Arduino beginners, students, IoT learners, and STEM projects, and it forms the base for security systems, motion alarms, and automation projects.
