Blind Stick With Ultrasonic Sensors

Echo pin of 1st sesnor.

Blind stick with ultrasonic sensors.

Const int buzz 13. Const int echo 2. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. On sensing obstacles the sensor passes this data to the microcontroller.

Const int trigger 3. Echo pin of 1st sesnor. Ultrasonic blind stick for completely blind people to avoid any kind of obstacles. 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.

In the circuit an arduino nano is used as the platform. Const int remote a0. 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. Echo pin of 1st sesnor.

Echo pin of 1st sesnor. Ultrasonic sensor is connected to arduino. Const int light a1. The system consists of ultra sonic sensor fixed to the user s stick.

Blind walking stick arduino ultrasonic sensor. 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 technology can indeed neutralize human disability.

Ultrasonic blind walking stick components used. 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. As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second.

Smart blind stick project using arduino and sensors. Trigger pin of 1st sesnor. 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 ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places.
