Welcome to this DIY Smart Stick project made with Arduino Nano, Ultrasonic Sensor (HC-SR04), and a Buzzer! 👨🔬
This project helps visually impaired people detect obstacles in their path using sound alerts. When the stick senses an object nearby, it triggers the buzzer to alert the user — making it a simple but powerful assistive technology.

🧠 How It Works
The ultrasonic sensor continuously measures the distance to nearby objects.
If the distance becomes less than 30 cm, the buzzer automatically turns ON, warning the user.
This efficient setup is perfect for beginners in electronics and robotics.
