Through this the blind person can be aware of the obstacles in front of him.
Smart blind stick using arduino uno project report.
Using this smart blind stick a visually impaired person can walk without anyone s help.
Ultrasonic blind walking stick using arduino circuit diagram.
The ldr is connected with a resistor of value 10k to form a potential divider and the difference in.
Ny idea for my project since im using vibrating motor and ultrasonic sensor for obstacle detection water sensor and.
Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator.
The stick uses ultrasonic sensors for obstacle detection.
The whole project has been designed on eagle.
We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
The same circuit prototype can be made using a breadboard or zero pcb.
Using this smart blind stick a visually impaired person can walk without anyone s help.
The ultrasonic sensor is powered by 5v and the trigger and echo pin is connected to arduino nano pin 3 and 2 as shown above.
Smart blind stick project using arduino and sensors.
This project is a smart stick which is capable of detecting any obstacle detect water and corners and even allow the user to find the stick if anyhow missed by the user by pressing a remote switch.
A 9 volt battery connector.
The device is designed with an intention to sort out common issues faced by the blind people while using traditional sticks.
The smart blind stick automatically detects the obstacle in front of the person and gives a response to the person by vibrating the stick and with a warning sound.
Person suffering from night blindness cataracts glaucoma albinism or injury.
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.
Dc male power jack.
A buzzer is connected between d9 pin of arduino and gnd pin.
Presented here is a smart stick using arduino uno.
