Displaying Moving Message On Notice Board Using PC
We
know that notice boards is primary thing to provide timely information in
public places like railway stations, bus stations and airports Hotels, Malls,
college, offices There are various ways available to display the message but In
many developing places where is still lack of internet access,
Television broadcasting access, we need to use a manual notice board and a separate person is required to take care of this
notices display as notices need to be change on day to day basis.
So to
solve this problem here we are introducing Display moving message on notice
board using pc .in this system pc is used to control the txt which is to be displayed on the notice board.
Block diagram:
In this project 8051 microcontroller is used for
controlling the whole process, and LCD to display the message. This system has two parts transmitter and receiver, in
transmitter part there is a PC with graphical user interface that allow user to
enter the message On the receiver part once the message received by the
receiver is taken to microcontroller which stores it, validates it and then
displays it on the moving Dot matrix LED display module.
The validation depends upon the stored letters on the microcontroller
in EEPROM which are compared with the incoming letters. This system contains
only the English capital characters (AZ) and numbers (0-9) .The numbers and
characters are stored in EEPROM can be edited only by the program
