Third Eye for the Blind

Individuals with visual disabilities often rely on external assistance, be it from humans, trained dogs, or specialized electronic devices, to aid their decision-making and navigation. The challenge lies in finding a way for the blind to navigate independently. According to the WHO, 10% of visually impaired individuals lack functional eyesight, necessitating constant assistance for safe mobility. This project addresses this issue by leveraging other senses such as sound and touch. It utilizes the Atmega-328 microcontroller, an advanced 8-bit AVR RISC-based microcontroller, along with the HC-SR04 Ultrasonic Range Finder Distance Sensor Module to measure distances using ultrasonic waves. The system incorporates a buzzer for alarm sounds and a motor for vibration signals, notifying the user of obstacles. As proximity decreases, both audio and vibration frequency increase, facilitating navigation for the visually impaired. This low-cost, reliable, portable, low power-consuming system offers a robust solution with quick response times.
