Smart Stick for Visually Impaired People

Hello there, we are making this projects with a help intention to people who are visually impaired and every time they need a helping hand to walking. now we are just introduce our smart stick for visually impaired people who need a helping hand. now with this device these people can walk without any person help.

We need some electronic components to make it work. working is very simple of this project you need to do the interface ultrasonic sensor to the Arduino. ultrasonic sensor can measure the distance simply. so we are using these ability of ultrasonic. we are detecting the object near to the stick.

we are using 3 ultrasonic sensor for three different direction. it can work in all the directions. so when any person or any object near to the stick it will notify the person who have the stick. we are using 2 vibration motor for left and right direction and one buzzer for forward direction.

we have posted all the working required circuit diagram and code on our website with step by step tutorial. you can go through the link.

Thanks.
