Blind Stick With Ultrasonic Sensors

Const int buzz 13.

Blind stick with ultrasonic sensors.

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. To design blind walking stick using. The technology can indeed neutralize human disability. In this project we will learn how to design blind.

Echo pin of 1st sesnor. Echo pin of 1st sesnor. Ultrasonic sensor is connected to arduino. The system consists of ultra sonic sensor fixed to the user s stick.

Const int remote a0. The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places. Const int light a1. Echo pin of 1st sesnor.

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. Blind walking stick arduino ultrasonic sensor. 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. On sensing obstacles the sensor passes this data to the microcontroller.

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. 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. Ultrasonic blind walking stick components used.

The blind stick is integrated with ultrasonic sensor along with light and water sensing. Const int echo 2. 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. Trigger pin of 1st sesnor.

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