Blind Walking Stick With Sensor Project

Smart blind stick project using arduino and sensors. 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.

This arduino smart blind stick project requires two separate circuits.

Blind walking stick with sensor project.

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. Almost 30 million people are blind according to the recent who report. In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. 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. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. You can buy all the required components used in this project from here. One is the main circuit which will be mounted on the blind man s stick.

The arduino uno then processes this data and calculates if the obstacle is close enough. The blind stick is integrated with ultrasonic sensor along with light and water sensing. These blind people are totally dependent on others as they can t walk alone. This is the reason why we have designed the blind walking stick device which will help blind people to walk with ease independently.

On sensing obstacles the sensor passes this data to the microcontroller. The main board s circuit diagram is shown below. On sensing obstacles the sensor passes this data to the arduino uno.
