Here we develop a tool which can serve as a blind stick being more efficient and helpful than the conventional one.
Smart blind stick using arduino ppt.
Smart blind stick project using arduino and 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.
The circuit diagram and pcb design are given below.
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.
A buzzer is connected between d9 pin of arduino and gnd pin.
This smart stick can help blind people walk on the street safely without any help.
The same circuit prototype can be made using a breadboard or zero pcb.
This will assist the blind persons during the walk and provides an alarm if any hurdle is detected within the set range.
I have used arduino pro mini because its smaller in size and can easily be placed on a blind.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
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.
Through this the blind person can aware about the obstacles in front of him.
Ultrasonic blind walking stick using arduino circuit diagram.
The smart stick is built on arduino pro mini.
Introduction presently blind people use a white stick as a tool for direction when they move or walk.
The whole project has been designed on eagle.
Smart blind stick blind people who suffer from a severe reduction in vision that cannot be corrected with conventional means such as refractive correction or medication and reduces a person s ability to function at certain or all tasks.
Here s a screenshot of smart blind stick using arduino in proteus isis.
Although blind persons can t read the values on lcd but still i have placed an lcd just to display all the values.
