This device is very useful for the people who surfering with eye blindness and this can able to detect the obstacles with the help of ultrasonic sensor.

2. Introduction
Presently, blind people use a white stick as a
tool for direction, when they move or walk.
Here, we develop a tool which can serve as a
blind stick being more efficient and helpful
than the conventional one.

3. Smart Blind Stick
Blind
People who suffer from a severe reduction in vision
that cannot be corrected with conventional means,
such as refractive correction or medication and
reduces a person’s ability to function at certain or all
tasks.

4. Components
• Arduino microcontroller
• Ultrasonic sensor (HC-SR04)
• LDR
• Power supply section (+5V)- onboard
• 7805 and 7812 regulators
• Soldering kit

5. • Buzzer
• Capacitor
• Dc jack male /female
• Transformer

6. Circuit Diagram

7. Applications
• Help blind people to easily walk to
destination.
• Help blind people for obstacle detection.
• Alert blind people about dig.

8. Advantages
• Auto detection.
• Having feature to left & right turn alarm
signal.
• Obstacle detection with indication support.
• Dig information with indication alarm.
• Simple to use & low cost

9. • Auto detection of station & speech message
will help blinds& physical disables to
recognize the destination.
• Auto alarming system
• Fully paperless system
• With little software & sensor up gradation,
can extensible to any other application &
specification.

10. Disadvantages
• Limited & fixed route to follow daily routine.
• Till now, GPS can’t attach in it due to 40 meter to change
coordinate as to follow the path/ new path.
• Little sensor support in these fields

11. Future scope
• GPS can help blind peoples to source &
destination route information.
• GPS can help to find the shortest & best path as
accordingly to Google/ Bing map based on real time
coordinates.
• GSM attachment can help in future for any
immediate causality help
