After msp430 powered the blind people can start using the smart blind stick.
Smart blind stick project.
Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves.
This arduino smart blind stick project requires two separate circuits.
This project is a smart stick which is capable of detecting any obstacle detect water and corners and even allow the user to find the stick if anyhow missed by the user by pressing a remote switch.
Using this smart blind stick a visually impaired person can walk without anyone s help.
Blind s mate is a combination of smart stick and a mobile app that can alert people of impending obstacles and water pits while providing audio feed to the users about obstacles encountered.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
Through this the blind person can aware about the obstacles in front of him.
The device is designed with an intention to sort out common issues faced by the blind people while using traditional sticks.
But with smart blind stick it will help them to get notification on the obstacle by a sound generated by buzzer.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
On sensing obstacles the sensor passes this data to the microcontroller.
In this project i have shown the features and functionalities of a smart blind stick which can be used by people who are visually impaired and have trouble.
One is the main circuit which will be mounted on the blind man s stick.
The main board s circuit diagram is shown below.
