Blind Stick With Ultrasonic Sensors

As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second.

Blind stick with ultrasonic sensors.

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. Const int light a1. In this project we will learn how to design blind. Const int buzz 13.

To design blind walking stick using. Ultrasonic blind stick for completely blind people to avoid any kind of obstacles. The technology can indeed neutralize human disability. The system consists of ultra sonic sensor fixed to the user s stick.

Echo pin of 1st sesnor. Const int remote a0. On sensing obstacles the sensor passes this data to the microcontroller. Echo pin of 1st sesnor.

In the circuit an arduino nano is used as the platform. Const int trigger 3. Arduino blind stick in action. Trigger pin of 1st sesnor.

Ultrasonic sensor is connected to arduino. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. 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 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. 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. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Smart blind stick project using arduino and sensors.

Const int echo 2. Echo pin of 1st sesnor. Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04. The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places.
