Project Overview
The Smart Blind Stick is an assistive device designed to help visually impaired people detect obstacles in front of them. It uses an ultrasonic sensor to measure the distance of objects and alerts the user using a buzzer when an obstacle is detected. This project improves safety and independence for blind individuals.

- Arduino UNO / Arduino Nano
- Ultrasonic Sensor (HC-SR04)
- Buzzer (Active Buzzer)
- Vibration Motor (Optional but Good Upgrade)
- LED (Optional)
- Jumper Wires
- Battery Pack (7–9V)
- Stick / PVC Pipe
- On / Off Switch
