Smart Blind Stick With Ultrasonic Sensor Using Arduino

This smart stick can help blind people walk on the street safely without any help.

Smart blind stick with ultrasonic sensor using arduino.

Almost 30 million people are blind according to the recent who report. 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 smart stick is built on arduino pro mini. Using this smart blind stick a visually impaired person can walk without anyone s help.

Person suffering from night blindness cataracts glaucoma albinism or injury. Ultrasonic sensor 2 buzzer led should be attached to breadboard. In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. 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.

These blind people are totally dependent on others as they can t walk alone. I used a mini breadboard to connect the ultrasonic sensor to the arduino using. 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. Ultrasonic sensor sends high frequency pulses these pulses reflects from object and takes as echo time between echo and trig is measured by the microcontroller or arduino which is.

Blind walking stick using arduino ultrasonic sensor hc sr04. The technology can indeed neutralize human disability. 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. 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. Obstacle detection is one of the major concerns for a fully or a partially blind person e g. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. The stick uses ultrasonic sensors for obstacle detection.
