Blind stick using ultrasonic sensors.

As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second. Abdul kalam technical. To design blind walking stick using. Ultrasonic navigation system for the blind submitted by abhishek dixit gagandeep singh mohit kumar pravin kumar under guidance of prof.

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 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. 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 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 abstract. The ability to live without being controlled by any action judgment and any outside factors including any opinions and regulations is defined by the term independent. Blind walking stick arduino ultrasonic sensor.

Smart blind stick project using arduino and sensors. On sensing obstacles the sensor passes this data to the microcontroller. All the feedbacks will be given to the blind man through a buzzer. The technology can indeed neutralize human disability.

The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places. Sensor based blind stick 1. 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.

In this project we will learn how to design blind. Ultrasonic blind walking stick components used.
