Smart Blind Stick With Ultrasonic Sensor Using Arduino

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.

Smart blind stick with ultrasonic sensor using arduino.

In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. 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. These blind people are totally dependent on others as they can t walk alone. 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 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. Using this smart blind stick a visually impaired person can walk without anyone s help.

The smart stick is built on arduino pro mini. This smart stick can help blind people walk on the street safely without any help. Person suffering from night blindness cataracts glaucoma albinism or injury. 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.

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. Project tutorial by hadi1234. Presented here is a smart stick using arduino uno. I used a mini breadboard to connect the ultrasonic sensor to the arduino using.

Ultrasonic sensor 2 buzzer led should be attached to breadboard. 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 uses ultrasonic sensors for obstacle detection. Blind walking stick using arduino ultrasonic sensor hc sr04.
