Abstract— This is the model for displaying notices in colleges on electronic notice board by sending messages in form of SMS through mobile; it is a wireless transmission system which has very less errors and maintenance. The hardware board contains microcontroller AT89c52 at the heart of the system. The microcontroller is interfaced with GSM Modem via MAX232 level convertor. It is used to convert RS232 voltage levels to TTL voltage levels and vice versa. The hardware also has a 64K EEPROM chip AT24C64. This EEPROM ....etc

SMS Based Wireless Electronic Notice Board using GSM/CDMA/3G Mobile Phone
ABSTRACT
Notice Board is primary thing in any institution / organization or public utility places like bus stations, railway stations and parks. But sticking various notices day-to-day is a difficult process. A separate person is required to take care of this notices display. This project deals about an advanced hi-tech wireless notice board.
The project is built around the ATMEGA8L micro controller from Atmel. This micro ....etc

GSM BASED DIGITAL NOTICE BOARD
INTRODUCTION
The user sends a SMS containing the data to be rolled.
PC receives the SMS and send it to both the slaves via RS232 -RS485 converter section.
Both the slaves receive the frame. Then they match the slave ID in the frame to their own ID’s.
If ID match occurs then that particular slave rolls the data on it’s alphanumeric display.

Bluetooth is a common thing in the modern world. However it is very useful to transfer data from one device to another. But this requires two Bluetooth devices which are very expensive. The aim of our project is to make wireless data logger. Details of the application end system are stored in memory. Whenever the remote system wants to download the application end system details, the remote system has to send corresponding command to end system through radio frequency. According to command the application end system send details of system throu ....etc
