Blind Walking Stick With Sensor Project

The arduino uno then processes this data and calculates if the obstacle is close enough.

Blind walking stick with sensor project.

On sensing obstacles the sensor passes this data to the arduino uno. 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. This arduino smart blind stick project requires two separate circuits.

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. 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.

Almost 30 million people are blind according to the recent who report. The main board s circuit diagram is shown below. The generally available blind walking sticks are capable of finding obstacle that touch the stick physically. It is helpful to a blind person but we here propose an advanced blond stick system that.

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. 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.
