Smart Blind Stick Using Ultrasonic Sensor

Smart blind stick project using arduino and sensors.

Smart blind stick using ultrasonic sensor. Blind stick is an innovative stick designed for visually disabled people for improved navigation. Almost 30 million people are blind according to the recent who report. 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. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.

Using this smart blind stick a visually impaired person can walk without anyone s help. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. The technology can indeed neutralize human disability.

In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. 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. 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. 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.

Blind walking stick using arduino ultrasonic sensor hc sr04. The smart stick is built on arduino pro mini. Obstacle detection is one of the major concerns for a fully or a partially blind person e g. An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.

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. Person suffering from night blindness cataracts glaucoma albinism or injury. This smart stick can help blind people walk on the street safely without any help. The blind stick is integrated with ultrasonic sensor along with light and water sensing.

These blind people are totally dependent on others as they can t walk alone.
