The blind stick is integrated with ultrasonic sensor along with light and water sensing.
Blind walking stick with sensor project.
Smart blind stick project using arduino and sensors.
One is the main circuit which will be mounted on the blind man s stick.
This is the reason why we have designed the blind walking stick device which will help blind people to walk with ease independently.
The arduino uno then processes this data and calculates if the obstacle is close enough.
The main board s circuit diagram is shown below.
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.
Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves.
These blind people are totally dependent on others as they can t walk alone.
On sensing obstacles the sensor passes this data to the microcontroller.
The generally available blind walking sticks are capable of finding obstacle that touch the stick physically.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
On sensing obstacles the sensor passes this data to the arduino uno.
This arduino smart blind stick project requires two separate circuits.
It is helpful to a blind person but we here propose an advanced blond stick system that.
