Blind Walking Stick With Sensor Project

This arduino smart blind stick project requires two separate circuits.

Blind walking stick with sensor project.

The blind stick is integrated with ultrasonic sensor along with light and water sensing. It is helpful to a blind person but we here propose an advanced blond stick system that. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves.

One is the main circuit which will be mounted on the blind man s stick. In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. This is the reason why we have designed the blind walking stick device which will help blind people to walk with ease independently.

Smart blind stick project using arduino and sensors. Almost 30 million people are blind according to the recent who report. The other is a small remote rf transmitter circuit which will be used to locate the main circuit. The generally available blind walking sticks are capable of finding obstacle that touch the stick physically.

On sensing obstacles the sensor passes this data to the arduino uno. The arduino uno then processes this data and calculates if the obstacle is close enough. The main board s circuit diagram is shown below.
