Arduino Nano Smart Blind Stick with Ultrasonic Sensor & Buzzer

Описание: Arduino Nano projects
In this video, we build a Smart Blind Stick using Arduino Nano, Ultrasonic Sensor (HC‑SR04), and a Buzzer. This project helps visually impaired individuals detect obstacles and navigate safely. Watch step‑by‑step as we assemble the circuit, write the code, and test the prototype.

🔧 Components Used:
Arduino Nano
HC‑SR04 Ultrasonic Sensor
Piezo Buzzer
Breadboard & Jumper Wires

💡 Features:
Obstacle detection using ultrasonic waves
Alert system with buzzer sound
Compact and portable design
