Smart Blind Stick Using Ultrasonic Sensor

These blind people are totally dependent on others as they can t walk alone.
Smart blind stick using ultrasonic sensor. With this in mind let us use the power of arduino and simple sensors to build a blind man s stick that could be a lifesaver for visually impaired persons. I used a mini breadboard to connect the ultrasonic sensor to the arduino using. Smart blind stick project using arduino and sensors. Almost 30 million people are blind according to the recent who report.
Blind stick is an innovative stick designed for visually disabled people for improved navigation. This smart stick can help blind people walk on the street safely without any help. Blind walking stick using arduino ultrasonic sensor hc sr04. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
The technology can indeed neutralize human disability. Using this smart blind stick a visually impaired person can walk without anyone s help. This arduino board is small enough to install on a regular stick and has buzzer ldr sensor ultrasonic sensor and a water detector sensor interfaced to it. Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
Presented here is a smart stick using arduino uno. The blind stick is integrated with ultrasonic sensor along with light and water sensing. The smart blind stick automatically detects the obstacle in front of the person and give him a response to the person by vibrating the stick and also with a warning sound. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing.
In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. Person suffering from night blindness cataracts glaucoma albinism or injury. The stick uses ultrasonic sensors for obstacle detection.
The smart stick is built on arduino pro mini.
