Smart blind stick project using arduino and sensors.
Smart blind stick using ultrasonic sensor pdf.
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.
Blind walking stick using arduino ultrasonic sensor hc sr04.
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.
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.
Using this smart blind stick a visually impaired person can walk without anyone s help.
In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04.
