Smart Blind Stick Using Arduino Code

Arduino program for smart blind stick.

Smart blind stick using arduino code.

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. 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. Using this smart blind stick a visually impaired person can walk without anyone s help. Code file is given in the link just download this file and upload to arduino.

In the code a library is used by the name ultrasonic h this library is not added in arduino by default. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator. Through this the blind person can aware about the obstacles in front of him.

Presented here is a smart stick using arduino uno. 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. Person suffering from night blindness cataracts glaucoma albinism or injury. The ldr is connected with a resistor of value 10k to form a potential divider and the difference in.

This smart stick can help blind people walk on the street safely without any help. Smart blind stick project using arduino and sensors. The stick uses ultrasonic sensors for obstacle detection. 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.

The smart stick is built on arduino pro mini. 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. However if you are curious to know how the code works read further.
