Ultrasonic Smart Glasses for the Blind
Project Idea:
A wearable assistive device that helps visually impaired individuals navigate their surroundings using ultrasonic sensors and vibration feedback. The system detects obstacles and alerts the user through silent vibrations, ensuring independence and safety without auditory disturbance.
 
Project Description:
The Ultrasonic Smart Glasses use two HC-SR04 ultrasonic sensors placed on both sides of the frame to detect objects and determine their distance. An ATmega328 microcontroller processes this data and activates mini vibrating motors accordingly. The glasses are powered by a rechargeable Li-ion battery and include supporting electronics like transistor-based driver circuits and LED indicators. The user experiences side-specific vibrations proportional to nearby obstacles, enabling real-time spatial awareness.
 
Components List:
  • ATmega328 microcontroller(Arduino Nano)
  • 1 × Sensors (HC-SR04/VL53L0X)
  • 1 × Vibration motors
  • 1 x Buzzer
  • Mini 5V Boost Converter Module
  • TP4056 Li-ion Charging Module
  • Li-ion rechargeable battery (3.7V)
  • Voltage regulator circuit
  • ON/OFF switch
  • Transparent glasses frame
