The Third Eye For The Blind Glasses - Pre Build Science Project With Report Pdf is an innovative wearable assistive device designed for visually impaired individuals. It uses an HC-SR04 ultrasonic sensor to detect obstacles and provides real-time alerts through a buzzer (sound), vibration motor (haptic feedback), and LED indicator (visual signal). Powered by an Arduino Nano and a 3.7V LiPo battery, the device is lightweight and rechargeable using a TP4056 charging module. The system is integrated into black glasses, making it a compact and hands-free solution. The closer the obstacle, the faster the buzzer beeps and vibration increases, helping users react quickly. This pre-built science project is perfect for engineering students, school science exhibitions, and research projects on assistive technology. It includes a detailed project report (PDF) for easy learning.
