Make an Obstacle Detector for Blind people using Ultrasonic Sensor Circuit Diagram
BlogMake an Obstacle Detector for Blind people using Ultrasonic Sensor Circuit Diagram 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.
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
Ultrasonic Blind Walking Stick Project Circuit Diagram
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. 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.
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

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,
