As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second.
Blind stick with ultrasonic sensors.
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.
Const int buzz 13.
On sensing obstacles the sensor passes this data to the microcontroller.
Blind walking stick arduino ultrasonic sensor.
Echo pin of 1st sesnor.
Smart blind stick project using arduino and sensors.
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.
Trigger pin of 1st sesnor.
This paper aims to design an artificial navigating system with adjustable sensitivity with the help of ultrasonic proximity sensor and a gps module to assist these blind persons to walk fearlesssly and independently in both indoor and outdoor environment.
The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places.
In the circuit an arduino nano is used as the platform.
Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves.

The system consists of ultra sonic sensor fixed to the user s stick.
Arduino blind stick in action.
To design blind walking stick using.
In this project we will learn how to design blind.

The blind stick is integrated with ultrasonic sensor along with light and water sensing.
Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04.
Ultrasonic blind stick for completely blind people to avoid any kind of obstacles.
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.
