Smart Blind Stick Project
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.
Smart blind stick project. Smart blind stick project using arduino and sensors. The blind stick is integrated with ultrasonic sensor along with light and water sensing. On sensing obstacles the sensor passes this data to the microcontroller. Read arduino isp log.
The other is a small remote rf transmitter circuit which will be used to locate the main circuit. The device is designed with an intention to sort out common issues faced by the blind people while using traditional sticks. After msp430 powered the blind people can start using the smart blind stick. 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. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. But with smart blind stick it will help them to get notification on the obstacle by a sound generated by buzzer. Using this smart blind stick a visually impaired person can walk without anyone s help.
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 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. 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.
The main board s circuit diagram is shown below. One is the main circuit which will be mounted on the blind man s stick.
