We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
Smart blind stick using arduino uno project report.
Ny idea for my project since im using vibrating motor and ultrasonic sensor for obstacle detection water sensor and.
The whole project has been designed on eagle.
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.
A buzzer is connected between d9 pin of arduino and gnd pin.
Dc male power jack.
The circuit diagram and pcb design are given below.
Presented here is a smart stick using arduino uno.
The same circuit prototype can be made using a breadboard or zero pcb.
Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
Using this smart blind stick a visually impaired person can walk without anyone s help.
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.
As we can see an arduino nano is used to control all the sensors.
The complete board is powered by a 9v battery which is regulated to 5v using a 7805 voltage regulator.
Ultrasonic blind walking stick using arduino circuit diagram.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
Using this smart blind stick a visually impaired person can walk without anyone s help.
The device is designed with an intention to sort out common issues faced by the blind people while using traditional sticks.
An ultrasonic sensor hcsr04.
Person suffering from night blindness cataracts glaucoma albinism or injury.
A 9 volt battery connector.
The ldr is connected with a resistor of value 10k to form a potential divider and the difference in.
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.
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.
