Figure 1 from Blind user wearable audio assistance for indoor Circuit Diagram To create this Blind Assistance System, several key components are utilized: Arduino Nano: The Arduino Nano serves as the central processing unit, coordinating signals from the ultrasonic sensor and GSM module. Its compact design and efficient processing capabilities make it perfect for wearable projects like this. Ultrasonic Sensor (HC-SR04):
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 Learn how to use the ultrasonic sensor (HC-SR04) with Arduino. This tutorial will teach you what it is, how to assemble the sensor on Arduino, and, at the end, you'll implement it into an alarm system project. Ultrasonic sensor with Arduino - Complete Guide. the range of 3m to 4m. The project is made by inspiring from the natural navigation system of a mammal called Bat. Although the navigation for blind using ultrasonic is a complex process but here we will present only the hurdle detection procedure. The project makes the use of UNO Arduino processor, ultrasonic sensors, 5V Buzzer,

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. Smart Blind Stick is an innovating stick designed for visually disable people for improved navigations. We here purpose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. Our purposed project first used ultrasonic sensor to detect obstacles ahead using ultrasonic waves.
