Скачать или смотреть IR Sensor Basics Explained ⚙️ How to use IR Sensor in Arduino UNO Projects ✨

In this video, I explain the IR Sensor basics in a simple and beginner-friendly way. I cover the working principle, pin configuration, and the active-low behavior that most IR sensors use. You’ll see exactly how I use the IR sensor with UNO in my Arduino projects, how the detection works, and how to avoid common beginner mistakes.

I also show how the IR module sends signals, how the IR LED + Photodiode work together, and why the output becomes LOW when an object is detected. This makes it easier for you to build your own Arduino IR projects confidently.

Whether you’re making counters, alarms, LED triggers, or obstacle detection, this video will help you understand the core concepts clearly.

✨ Topics I cover naturally in this video:
• IR sensor working principle
• IR sensor pin configuration (VCC, GND, OUT)
• Active low output explanation
• How I connect an IR sensor with UNO
