Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
Smart blind stick using arduino uno project report.
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.
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.
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.
Person suffering from night blindness cataracts glaucoma albinism or injury.
An ultrasonic sensor hcsr04.
The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator.
The device is designed with an intention to sort out common issues faced by the blind people while using traditional sticks.
Dc male power jack.
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.
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.
We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
The circuit diagram and pcb design are given below.
A 9 volt battery connector.
Ny idea for my project since im using vibrating motor and ultrasonic sensor for obstacle detection water sensor and.
A buzzer is connected between d9 pin of arduino and gnd pin.
The same circuit prototype can be made using a breadboard or zero pcb.
Through this the blind person can be aware of the obstacles in front of him.
The ldr is connected with a resistor of value 10k to form a potential divider and the difference in.
As we can see an arduino nano is used to control all the sensors.
Ultrasonic blind walking stick using arduino circuit diagram.
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.
