Smart Blind Stick Project

The blind stick is integrated with ultrasonic sensor along with light and water sensing.

Smart blind stick project.

The device is designed with an intention to sort out common issues faced by the blind people while using traditional sticks. Based on the observation on the traditional white cane the blind people will always swing around the blind stick to get a confirmation on their surrounding. 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.

This arduino smart blind stick project requires two separate circuits. One is the main circuit which will be mounted on the blind man s stick. Smart blind stick project using arduino and sensors. On sensing obstacles the sensor passes this data to the microcontroller.

Read arduino isp log. 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. After msp430 powered the blind people can start using the smart blind stick.

The main board s circuit diagram is shown below. 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. Through this the blind person can aware about the obstacles in front of him. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves.

The other is a small remote rf transmitter circuit which will be used to locate the main circuit. The other is a small remote rf transmitter circuit which will be used to locate the main circuit.
