🚨 DIY Arduino Alarm System with Buzzer & Ultrasonic Sensor! 🔊

Want to build a simple motion detection alarm using Arduino? This project uses an ultrasonic sensor (HC-SR04) to detect objects, and if something comes too close, a buzzer instantly alerts you! 🚀

🛠 What You'll Need:
✅ Arduino board
✅ Ultrasonic sensor (HC-SR04)
✅ Buzzer
✅ Jumper wires
✅ Arduino IDE for coding

🔍 How It Works:
1️⃣ The ultrasonic sensor detects an object within a set distance.
2️⃣ If an object enters the detection range, the buzzer automatically turns ON!
3️⃣ Perfect for home security, robotics, and fun DIY projects!
