Basic Block Diagram of proposed ultrasonic navigation system for blind Circuit Diagram Also we use a shorting system to detect water in front of the person. As soon as the front wires of the system dip in water that system signals the blind person by a different beep pattern to signal water in front. Now this system also has a light sensing feature to give the blind person a sense of light.
Blind stick is an innovative stick designed for visually disabled people for improved navigation. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. The blind stick is integrated with ultrasonic sensor along with light and water sensing.

Obstacle Detection: The ultrasonic sensor accurately measures distances and detects obstacles in the user's path. Real-time Feedback: The system provides real-time audio feedback through a buzzer, indicating the proximity of objects. Adjustable Warning Levels: The buzzer emits different frequencies and durations of sound based on the distance of detected objects.
Fix your Arduino in the box using screws. Now make two holes for fixing the ultrasonic sensor on the lid of the box as shown in the above image. I attached the buzzer outside of the box for better sound. Next, I attached the toggle switch at the side of the box and made a small hole for connecting the vibration motor to the Arduino. This is a navigation assistant for the visually impaired, not necessarily just for the 'blind,' but rather it is a useful tool for anyone with blurry vision or difficulty seeing, legally blind or otherwise. It uses an ultrasonic sensor - HC-SR04 - to 'read' the environment and get a distance reading, while a buzzer relays the distances to the

Some sticks contain an ultrasonic distance sensor to detect obstacles. An ultrasonic sensor emits a burst of ultrasonic sound and measures how long it takes the sound wave to reflect back to the sensor - just like a bat uses sonar to echolocate objects. The stick can then provide some sort of feedback to the user - like a beep or vibration - to
