Smart Blind Stick Using Arduino Code

Through this the blind person can aware about the obstacles in front of him.

Smart blind stick using arduino code.

This arduino board is small enough to install on a regular stick and has buzzer ldr sensor ultrasonic sensor and a water detector sensor interfaced to it. Code file is given in the link just download this file and upload to arduino. The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator. This smart stick can help blind people walk on the street safely without any help.

Ultrasonic blind walking stick program code. Person suffering from night blindness cataracts glaucoma albinism or injury. Presented here is a smart stick using arduino uno. In the code a library is used by the name ultrasonic h this library is not added in arduino by default.

Once we are ready with our hardware we can connect the arduino to our computer and start programming. The smart stick is built on arduino pro mini. Smart blind stick using arduino with ultrasonic sensor and ir sensor smart blind walking stick science project using ultrasonic sensor arduino blind st. The ldr is connected with a resistor of value 10k to form a potential divider and the difference in.

Using this smart blind stick a visually impaired person can walk without anyone s help. As we can see an arduino nano is used to control all the sensors. The ultrasonic sensor is powered by 5v and the trigger and echo pin is connected to arduino nano pin 3 and 2 as shown above. The smart blind stick automatically detects the obstacle in front of the person and give him a response to the person by vibrating the stick and also with a warning sound.

This is a arduino code which you can run on arduino ide. The complete code used for this page can be found at the bottom of this page you can upload it directly to your arduino board. Obstacle detection is one of the major concerns for a fully or a partially blind person e g. The stick uses ultrasonic sensors for obstacle detection.

However if you are curious to know how the code works read further. By this the person using the blind stick will be able to know is there any obstacle on his way so that he she will be alert.
