In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04.
Smart blind stick using ultrasonic sensor.
An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.
The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing.
Smart blind stick project using arduino and sensors.
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.
The stick uses ultrasonic sensors for obstacle detection.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
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 technology can indeed neutralize human disability.
These blind people are totally dependent on others as they can t walk alone.
Presented here is a smart stick using arduino uno.
Almost 30 million people are blind according to the recent who report.
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.
Ultrasonic sensor 2 buzzer led should be attached to breadboard then we should connect these components to arduino by wires after that the circuit should be attached to a stick with a tape.
The smart stick is built on arduino pro mini.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
Blind walking stick using arduino ultrasonic sensor hc sr04.
Person suffering from night blindness cataracts glaucoma albinism or injury.
We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
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.
