Smart Blind Stick Using Arduino Code

This is a arduino code which you can run on arduino ide.
Smart blind stick using arduino code. Person suffering from night blindness cataracts glaucoma albinism or injury. Smart blind stick using arduino with ultrasonic sensor and ir sensor smart blind walking stick science project using ultrasonic sensor arduino blind st. 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. As we can see an arduino nano is used to control all the sensors.
Smart blind stick project using arduino and sensors. 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. Presented here is a smart stick using arduino uno. This smart stick can help blind people walk on the street safely without any help.
Once we are ready with our hardware we can connect the arduino to our computer and start programming. Using this smart blind stick a visually impaired person can walk without anyone s help. The smart stick is built on arduino pro mini. Arduino program for smart blind stick.
The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. However if you are curious to know how the code works read further. 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. Ultrasonic blind walking stick program code.
Code file is given in the link just download this file and upload to arduino. Obstacle detection is one of the major concerns for a fully or a partially blind person e g. 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. 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. In the code a library is used by the name ultrasonic h this library is not added in arduino by default.
