3. ABOUT…
 In the society, there exists lack or difficulty of communication among
the differently abled.
 A communication system for dumb, deaf and blind.
 Vibrations can be sensed by the skin.
 Low cost & Affordable.

4. COMPONENTS
 Arduino UNO
 Vibration Motor
 Laptop
 Microphone
 Wrist Watch Module

5. Details
 Voice input is converted into corresponding vibration in the wrist
watch tied.
 Morse code is implemented to represent the alphabets.
 Morse code is programmed in the Arduino.
 First the input voice converted to text by using python language.
 Laptop is used as input & power supply.

8. PROGRAMMING
 To convert voice input to text.
Step 1:
Voice input is recorded.
Step 2:
Recorded voice is send to google.
Step 3:
Corresponding text are received.
Python Program

9. PROGRAMMING
 Morse Code is programmed in Arduino.
 Alphabets are coded according to Morse code standards.
 Input for the Arduino is given from the laptop (ie,output of
python program).
 Separate time length(delay) are given to dots, dashes, short space
and space.

10. PROGRAMMING
 Dot 300 ms
 Dash 900 ms
 Short Space 600 ms
 Space 1200 ms
 Acc. To IN standards, 1 dash = 3 dots
Time Lengths
Arduino Program

11. MORSE CODE
 Morse code is a character encoding scheme used in
telecommunication that encodes text characters as standardized
sequences of two different signal durations called dots and
dashes.
 Each Morse code symbol is formed by a sequence of dots and
dashes.
 The dot duration is the basic unit of time measurement in Morse
code transmission.
 The duration of a dash is three times the duration of a dot.

14. MODIFICATIONS
 Vibrator circuits can be replaced by
LED or beep circuits.
 Circuitry can be implemented to small
devices such as smart watches using
MicroPython.

15. MODIFICATIONS
 Can be used in smart
phones.
 Morse code can be
replaced with custom
codes.

16. Advantages
 A better communication way for the Differently abled persons.
 Low cost.
 User Friendly.
 Can be modified according to requirements.

17. Disadvantages
 Complicated training which requires long time.
 Internet is necessary for the efficient working.
 Comparatively Slower process.
 More accuracy and precision can not be guaranteed.

18. OVERVIEW
 Used for most of the persons whether they are dumb, deaf and blind.
 It is Reliable.
 It is Cheaper.
 It is Sustainable since it can be maintained.
 Specifications may varied according to the usage of vibration motor
and software used for the program.

19. CONCLUSION
 An efficient method or device that can be used for the
communication is developed.
 As per requirements it can be modified.
 Implemented on objects that we are much familiar with such as
smart phones.
 Since highly developed devices are not present in the market, the
device can be used.
