Abstract: Obstacle detection for the blind using ultrasonic sensor is an innovative approach designed to enhance the mobility and safety of visually impaired individuals. This system utilizes ultrasonic sensors to detect objects in the user's path by emitting high-frequency sound waves, which bounce off nearby obstacles and are reflected back to the sensor. The sensor processes the reflected signals to determine the distance to obstacles and provides real-time feedback to the user through auditory signals. This enables individuals to navigate their environment more effectively, avoiding potential collisions and hazards. The primary objective of this project is to assist blind individuals in navigating their surroundings safely and independently, avoiding potential hazards.
