Through this the blind person can aware about the obstacles in front of him.
Smart blind stick using arduino ppt.
Smart blind stick project using arduino and sensors.
I have used arduino pro mini because its smaller in size and can easily be placed on a blind.
A buzzer is connected between d9 pin of arduino and gnd pin.
The whole project has been designed on eagle.
Using this smart blind stick a visually impaired person can walk without anyone s help.
Although blind persons can t read the values on lcd but still i have placed an lcd just to display all the values.
Presently blind people use a white stick as a tool for directing them when they move or walk.
The same circuit prototype can be made using a breadboard or zero pcb.
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.
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 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.
Here s a screenshot of smart blind stick using arduino in proteus isis.
The circuit diagram and pcb design are given below.
The smart stick is built on arduino pro mini.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
This smart stick can help blind people walk on the street safely without any help.
This will assist the blind persons during the walk and provides an alarm if any hurdle is detected within the set range.
Ultrasonic blind walking stick using arduino circuit diagram.
Here we develop a tool which can serve as a blind stick being more efficient and helpful than the conventional one.
