Blind Stick With Ultrasonic Sensors

Ultrasonic blind walking stick components used.

Blind stick with ultrasonic sensors.

Const int trigger 3. On sensing obstacles the sensor passes this data to the microcontroller. Trigger pin of 1st sesnor. 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.

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. Echo pin of 1st sesnor. Ultrasonic sensor is connected to arduino. Const int buzz 13.

Ultrasonic blind stick for completely blind people to avoid any kind of obstacles. Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04. In the circuit an arduino nano is used as the platform. Blind walking stick arduino ultrasonic sensor.

Const int light a1. 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. The blind stick is integrated with ultrasonic sensor along with light and water sensing. As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second.

Const int echo 2. Const int remote a0. 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. Smart blind stick project using arduino and sensors.

Echo pin of 1st sesnor. In this project we will learn how to design blind. The technology can indeed neutralize human disability. 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.

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. To design blind walking stick using. Echo pin of 1st sesnor.
