DIY Smart Obstacle Avoidance Glasses using Arduino | Ultrasonic Sensor

What if a simple pair of glasses could save someone from walking into danger? In this video, I build DIY Smart Obstacle Avoidance Glasses using an Arduino Nano and HC-SR04 ultrasonic sensor — a wearable assistive tech project that detects obstacles in real time and alerts the user through a buzzer and vibration motor. Perfect for the visually impaired and an amazing beginner Arduino build! We'll cover everything from scratch — how the ultrasonic sensor works, circuit wiring, coding in Arduino IDE, and mounting it all on a glasses frame. Let's build something that actually matters. ✅ Detects obstacles up to 400 cm ✅ Real-time buzzer + vibration alert ✅ Runs on 9V battery — fully portable ✅ Beginner friendly — full code provided 📦 Components used: — Arduino Nano — HC-SR04 Ultrasonic Sensor — Buzzer — 9V Battery + clip — Old glasses frame — Jumper wires 💾 Full Code: https://propelxlabs.com/
