Blind Stick With Ultrasonic Sensors

Echo pin of 1st sesnor.

Blind stick with ultrasonic sensors.

Trigger pin of 1st sesnor. Echo pin of 1st sesnor. The system consists of ultra sonic sensor fixed to the user s stick. Const int remote a0.

Smart blind stick project using arduino and sensors. On sensing obstacles the sensor passes this data to the microcontroller. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Const int buzz 13.

Const int light a1. Echo pin of 1st sesnor. The technology can indeed neutralize human disability. 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.

Const int trigger 3. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. Ultrasonic sensor is connected to arduino. Const int echo 2.

The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places. Echo pin of 1st sesnor. In this project we will learn how to design blind. 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 walking stick components used. 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. Blind walking stick arduino ultrasonic sensor. Ultrasonic blind stick for completely blind people to avoid any kind of obstacles.

To design blind walking stick using. Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04. 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 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.
