Const int buzz 13.
Blind stick with ultrasonic sensors.
Const int echo 2.
The remote built on rf transmitter has a switch pressing which the buzzer installed on the stick is triggered and by the sound of the buzzer a blind person can find the stick.
Echo pin of 1st sesnor.
An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to sense lighting conditions and an rf remote which the blind man could use to remotely locate his stick.

As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second.
Trigger pin of 1st sesnor.
Const int trigger 3.
Arduino blind stick in action.
In the circuit an arduino nano is used as the platform.
In this project we will learn how to design blind.
Const int remote a0.
Smart blind stick project using arduino and sensors.
Blind walking stick arduino ultrasonic sensor.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
While the user moves the stick in the forward direction the ultrasonic sensor fixed to the stick tries to detect the obstacle if any present in the path.
Ultrasonic sensor is connected to arduino.
The system consists of ultra sonic sensor fixed to the user s stick.
Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04.
With this in mind let us use the power of arduino and simple sensors to build a blind man s stick that could be a lifesaver for visually impaired persons.
The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places.
Ultrasonic blind walking stick components used.
The technology can indeed neutralize human disability.
Const int light a1.
To design blind walking stick using.
Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves.
On sensing obstacles the sensor passes this data to the microcontroller.
