🚀 Ultrasonic Sensor with LED | Obstacle Detection Using Arduino 🎯

Welcome to another exciting Arduino tutorial! In this video, we will show you how to use an HC-SR04 Ultrasonic Sensor to detect obstacles and control an LED based on the measured distance. This is a perfect project for beginners and hobbyists who want to learn sensor-based automation. 🎉

📌 What You'll Learn in This Video:
✅ How the HC-SR04 Ultrasonic Sensor works 📡
✅ How to connect the HC-SR04 to an Arduino Uno 🤖
✅ How to measure distance using pulseIn() function ⏱️
✅ How to control an LED based on object proximity 💡
✅ How to write simple Arduino code for obstacle detection 📝

🛠️ Required Components:
To complete this project, you will need:

🔹 Arduino Uno (or any compatible board)
🔹 HC-SR04 Ultrasonic Sensor
🔹 LED (Any color)
🔹 220Ω Resistor
🔹 Jumper Wires
🔹 Breadboard (optional)

⚡ How Does It Work?
The HC-SR04 ultrasonic sensor emits a high-frequency sound wave from its Trig (Trigger) pin. When this wave hits an obstacle, it bounces back to the Echo pin. The Arduino calculates the time it takes for the wave to return and converts it into distance (cm) using the formula:

📏 Distance = (Time × Speed of Sound) / 2

If the detected distance is less than or equal to 10 cm, the LED turns ON. Otherwise, it remains OFF. This is useful for robotics, automation, and security applications. 🚀

🔌 Circuit Diagram & Wiring:
HC-SR04 Pin Arduino Pin
VCC to 5V
Trig to D9
Echo to D10
GND to GND
LED Pin Arduino Pin
(Anode) to D6 (through 220Ω resistor)
(Cathode) to GND

🔎 How to Test This Project?
1️⃣ Upload the code to your Arduino Uno using the Arduino IDE.
2️⃣ Open the Serial Monitor (Ctrl + Shift + M) to view the distance readings.
3️⃣ Place an object in front of the ultrasonic sensor and move it closer or farther.
4️⃣ If the object is within 10 cm, the LED will turn ON.
5️⃣ If the object is farther than 10 cm, the LED will turn OFF.

🚀 Applications of This Project:
🎯 Obstacle Avoidance Robots – Used in autonomous vehicles and robots.
🎯 Smart Security Systems – Detects motion and triggers alarms.
🎯 Automatic Door Systems – Opens doors when a person is detected.
🎯 Industrial Automation – Detects objects on conveyor belts.
🎯 Parking Sensors – Helps vehicles avoid obstacles while parking.
