Blind Goggles Project with Ultrasonic Sensors for Obstacle Detection

Blind Goggles Project for Obstacle Detection with Ultrasonic Sensors

Product Overview / Introduction:
The Blind Goggles project is an innovative technology designed to help individuals navigate their surroundings safely. Using advanced ultrasonic sensors, this project provides real-time obstacle detection and navigation assistance. With three ultrasonic sensors strategically placed (left, middle, and right), the system detects obstacles from all directions. Additionally, the LDR sensor adjusts the response based on light levels, offering enhanced performance in day and night conditions. The 5V buzzer produces an alert sound when an obstacle is detected, guiding the user. Powered by a TP4056 Type-C module and a power bank, the project offers mobility and long-lasting power. The goggles are made from durable 5mm PVC board, assembled with glue stick for stability and strength. The project is controlled via the Arduino Nano Type B, offering flexibility and ease of customization for DIY enthusiasts and science project creators. This product is perfect for those interested in science, technology, and innovation. Whether you're a student, hobbyist, or an educator, this project provides both functional and educational value.
