The smart stick is built on arduino pro mini.
Smart blind stick with ultrasonic sensor using arduino. The stick uses ultrasonic sensors for obstacle detection. The technology can indeed neutralize human disability. Presented here is a smart stick using arduino uno. Blind walking stick using arduino ultrasonic sensor hc sr04.
In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. I used a mini breadboard to connect the ultrasonic sensor to the arduino using. Ultrasonic sensor 2 buzzer led should be attached to breadboard. 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.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. Almost 30 million people are blind according to the recent who report. These blind people are totally dependent on others as they can t walk alone. 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.
Obstacle detection is one of the major concerns for a fully or a partially blind person e g. 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. An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to. Project tutorial by hadi1234.
The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. Person suffering from night blindness cataracts glaucoma albinism or injury. Ultrasonic blind walking stick as shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second is receiver or echo. 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.
