Smart Blind Stick With Ultrasonic Sensor

For better accuracy and assistance two or three ultrasonic sensors sensors can be added to this project.
Smart blind stick with ultrasonic sensor. These blind people are totally dependent on others as they can t walk alone. Through this the blind person can aware about the obstacles in front of him. I used ultrasonic sensor for detecting the obstacles. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. This is the reason why we have designed the blind walking stick device which will help blind people to walk with ease independently. It cost me just 10 to make one. 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.
The smart stick is built on arduino pro mini. Blind stick is an innovative stick designed for visually disabled people for improved navigation. This smart stick will have an ultrasonic sensor to sense distance from any obstacle ldr to sense lighting conditions and a rf remote using which the blind man could remotely locate his stick all the feedbacks will be given to the blind man through a buzzer.
