In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04.
Electronic walking stick for blind project.
The electronic walking stick will help the blind person by providing more convenient means of life.
Simulation of the blind stick via proteus 8 0 fig.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
Check if there is water in front.
Short paper an intelligent walking stick for the visually impaired people fig.
It is generally comprised of a supporting rod a control box a handle a free steering caster.
This smart stick will have an ultrasonic sensor to sense distance from any obstacle ldr to sense lighting conditions and a rf remote using which the blind man could remotely locate his stick all the feedbacks will be given to the blind man through a buzzer.
They even cannot walk on their own.
According to the who about 30 million people are estimated to be permanently blind worldwide.
We have created designed and built an ultrasonic blind walking stick device which will help blind people to walk with ease.
The main aim of this paper is to contribute our knowledge and services to the people of blind.

The generally available blind walking sticks are capable of finding obstacle that touch the stick physically.
This invention relates to an electronic talking stick for the blind and more particularly to a stick which talks to instruct a blind man to walk and go upstairs and downstairs and to warn a blind man of dangerous depression in road and which calls for help when a blind man who uses the stick falls.
These blind people are totally dependent on others as they can t walk alone.
Ultrasonic blind walking stick.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
It is helpful to a blind person but we here propose an advanced blond stick system that allows blind person to sense objects before stick touches them.
