Blind Stick Using Ultrasonic Sensors

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 stick using ultrasonic sensors.

In this project we will learn how to design blind. All the feedbacks will be given to the blind man through a buzzer. As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second. On sensing obstacles the sensor passes this data to the microcontroller.

This smart stick will have an ultrasonic sensor to sense distance from any obstacle ldr to sense lighting conditions and a rf remote using which the blind man could remotely locate his stick. Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04. Blind walking stick arduino ultrasonic sensor. Ultrasonic navigation system for the blind submitted by abhishek dixit gagandeep singh mohit kumar pravin kumar under guidance of prof.

Smart blind stick project using arduino and sensors. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places. The blind stick is integrated with ultrasonic sensor along with light and water sensing.

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. Gangwar project incharge department of electronics engineering kamla nehru institute of technology sultanpur 228118 u p dr. Abdul kalam technical. In the circuit an arduino nano is used as the platform.

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. Ultrasonic blind stick for completely blind people to avoid any kind of obstacles abstract. Ultrasonic sensor is connected to arduino. Sensor based blind stick 1.

The technology can indeed neutralize human disability. To design blind walking stick using.
