This smart stick can help blind people walk on the street safely without any help.
Smart blind stick with ultrasonic sensor documentation.
Ultrasonic sensor sends high frequency pulses these pulses reflects from object and takes as echo time between echo and trig is measured by the microcontroller or arduino which is.
We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
Person suffering from night blindness cataracts glaucoma albinism or injury.
For better accuracy and assistance two or three ultrasonic sensors sensors can be added to this project.
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 smart stick is built on arduino pro mini.
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.
Ultrasonic blind walking stick as shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second is receiver or echo.
These blind people are totally dependent on others as they can t walk alone.
Smart blind stick using arduino with ultrasonic sensor and ir sensor 28.
He has named this stick as smart blind stick.
Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
Smart blind stick with ultrasonic sensor documentation 26.
The technology can indeed neutralize human disability.
Smart blind stick using.
Ultrasonic sensor 2 buzzer led should be attached to breadboard then we should connect these components to arduino by wires after that the circuit should be attached to a stick with a tape.
Rf transmitter and receiver the stick is also equipped with light dependent resistor ldr sensor and an ultrasonic sensor informs sajal.
An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.
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.
With this in mind let us use the power of arduino and simple sensors to build a blind man s stick that could be a lifesaver for visually impaired persons.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
Presented here is a smart stick using arduino uno.
The stick uses ultrasonic sensors for obstacle detection.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
