Smart Blind Stick Project

One is the main circuit which will be mounted on the blind man s stick.

Smart blind stick project.

The blind stick is integrated with ultrasonic sensor along with light and water sensing. But with smart blind stick it will help them to get notification on the obstacle by a sound generated by buzzer. 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 main board s circuit diagram is shown below.

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. 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. 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.

Using this smart blind stick a visually impaired person can walk without anyone s help. Smart blind stick project using arduino and sensors. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. Read arduino isp log.

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. This arduino smart blind stick project requires two separate circuits. Through this the blind person can aware about the obstacles in front of him. One is the main circuit which will be mounted on the blind man s stick.

This arduino smart blind stick project requires two separate circuits. The device is designed with an intention to sort out common issues faced by the blind people while using traditional sticks.
