Blind Stick With Ultrasonic Sensors

Echo pin of 1st sesnor.

Blind stick with ultrasonic sensors.

Echo pin of 1st sesnor. Ultrasonic blind walking stick components used. 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. Smart blind stick project using arduino and sensors.

Const int echo 2. Echo pin of 1st sesnor. Const int remote a0. The system consists of ultra sonic sensor fixed to the user s stick.

In the circuit an arduino nano is used as the platform. 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. As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second. Arduino blind stick in action.

Blind walking stick arduino ultrasonic sensor. Trigger pin of 1st sesnor. Const int light a1. 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.

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. Const int trigger 3. The technology can indeed neutralize human disability. Ultrasonic sensor is connected to arduino.

Ultrasonic blind stick for completely blind people to avoid any kind of obstacles. 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. Const int buzz 13.
