Presented here is a smart stick using arduino uno.
Smart blind stick using arduino uno project report.
Using this smart blind stick a visually impaired person can walk without anyone s help.
Ny idea for my project since im using vibrating motor and ultrasonic sensor for obstacle detection water sensor and.
Smart blind stick project using arduino and sensors.
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.
The circuit diagram and pcb design are given below.
The same circuit prototype can be made using a breadboard or zero pcb.
The stick uses ultrasonic sensors for obstacle detection.
The ldr is connected with a resistor of value 10k to form a potential divider and the difference in.
A buzzer is connected between d9 pin of arduino and gnd pin.
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.
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.

The whole project has been designed on eagle.
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.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
The device is designed with an intention to sort out common issues faced by the blind people while using traditional sticks.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
Through this the blind person can be aware of the obstacles in front of him.

Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
