Smart Blind Stick Using Arduino Code

In the code a library is used by the name ultrasonic h this library is not added in arduino by default.

Smart blind stick using arduino code.

The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator. 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. 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. 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. The stick uses ultrasonic sensors for obstacle detection. However if you are curious to know how the code works read further. As we can see an arduino nano is used to control all the sensors.

The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. Ultrasonic blind walking stick program code. 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. Through this the blind person can aware about the obstacles in front of him.
