The document discusses an Arduino-based electronic notice board that utilizes GSM technology for communication and home appliance control via SMS. It outlines objectives such as displaying messages and controlling devices remotely, while contrasting existing methods like Bluetooth and Zigbee. The proposed system aims to enhance communication efficiency, reduce wiring complexity, and expand operational range, making it suitable for various applications like advertisements and educational institutions.

4. INTRODUCTION
• IT PRESENTS AN SMS NOTICE BOARD INCORPORATING
THE WIDELY USED GSM TO FACILITATE THE
COMMUNICATION OF DISPLAYING MESSAGE ON NOTICE
BOARD VIA USER’S MOBILE PHONE.
• IT IS FURTHER DISPLAYED ON AN ELECTRONIC NOTICE
BOARD WHICH EQUIPPED WITH LED DISPLAY.
• IN THIS WE ARE IMPLEMENTING USING ARDUINO AND
WHICH IS ALSO USEFUL TO CONTROL THE HOME
APPLIANCES.

5. OBJECTIVES
• TO DISPLAY THE MESSAGE ON NOTICE BOARD
THROUGH SMS.
• TO EFFECTIVELY RECEIVE AND TRANSMIT DATA VIA
SMS
• TO CONTROL THE HOME APPLIANCES THROUGH SMS

6. LITERATURE SURVEY
• IN TODAY WORLD COMMUNICATION PLAYS A MAJOR
ROLE WITH FAST GROWING TECHNOLOGIES
• OUR WISH IS TO CONTROL EVERYTHING WITH OUT
MOVING AN INCH
• IN PRESENT DIGITISED WORLD GSM BECAME MORE
POPULAR . SO BY USING GSM WE CAN ACCESS FROM
ANYWHERE AND EVERYWHERE.

7. EXISTING METHODS
• WIRELESS ELECTRONIC NOTICE BOARD USING
BLUETOOTH
• WIRELESS ELECTRONIC NOTICE BOARD USING
ZIGBEE
• WIRELESS ELECTRONIC NOTICE BOARD USING
89S52

8. LIMITATIONS
• COMMUNICATION RANGE CONFINED TO
100M ONLY
• SHORT RANGE OF COMMUNICATION

9. PROPOSED METHOD
ARDUINO BASED WIRELESS
ELECTRONIC NOTICE BOARD AND
SMART HOME USING GSM

11. FLOWCHART

13. BLOCK DIAGRAM

14. GSM MODEM
• QUAD BAND GSM
• HIGH QUALITY
• CONFIGURABLE BAUD
RATE
• BUILT IN SIM CARD
HOLDER
• BUILT IN CONVERTER

15. ARDUINO-UNO
• MICROCONTROLLER
• OPERATING VOLTAGE-5V
• ANALOG INPUT PINS-6
• DIGITAL I/O PINS-14
• CLOCK SPEED
• USB INTERFACE

16. LED DISPLAY
• FLAT PANEL DISPLAY
• BRIGHTNESS IS MORE
• USED IN PUBLIC
TRANSPORT VEHICLES

17. METHODOLOGY
STEP 1: INITIALISE THE LED DISPLAY
STEP 2: INTIALISE THE GSM MODULE
STEP 3: FIRST CLEAR ALL THE MESSAGES
STEP4: READ THE STRINGS AND GIVE THE
COMMANDS

18. WORKING
• SEND THE MESSAGE TO THE SIM INSERTED IN GSM
MODEM WITH THE HELP OF MOBILE
• CONTROL THE HOME APPLIANCES WITH THE HELP OF
MESSAGES SENT FROM THE MOBILE

19. RESULTS

20. WHEN THE MESSAGE IS GIVEN

21. CONTROLLING OF FAN

22. CONTROLLING OF LIGHT

23. CLEARING THE
MESSAGES

24. ADVANTAGES
• NO NEED OF COMPLEX WIRES
• CONSUMES LESS POWER
• LONG RANGE OF COMMUNICATION
• EASY TO CONTROL FROM ANYWHERE

25. DISADVANTAGES
• COST
• NETWORK ISSUES

26. APPLICATIONS
• USED FOR ADVERTISEMENTS
• TO DISPLAY MESSAGES IN EDUCATIONAL
INSTITUTIONS
• IN RAILWAY STATIONS , BUS STATIONS ,
HOSPITALS
• STOCK EXCHANGES
• TRAFFIC LIGHT CONTROL

27. CONCLUSION
• BY USING THIS PROJECT, WE CAN TRANSMIT
THA DATA OVER A LONG DISTANCE RANGE OF
COMMUNICATION WITH THE HELP OF GSM AND
WE CAN CONTROL THE HOME APPLIANCES BY
SENDING THE MESSAGES THROUGH THE MOBILE

28. FUTURE SCOPE
• IN THE APPLICATION OF HOME AUTOMATION WE CAN
CONTROL THE APPLIANCES LIKE MICROWAVE OVEN,
REFRIDGERATOR , WASHING MACHINES ETC.,
• PROVIDING SECURITY SYSTEM FROM
UNAUTHENTICATED USERS BY USING PASSWORD
SYSTEM
