Timed Announcement and Billboard with Internet Access

Announcement and advertisement board were designed and realized in this study. Data is sent to the board over the internet using UDP User Datagram Protocol protocol. The announcement data sent to the clipboard is printed on the clipboard at the specified time interval. A web interface has been created for sending announcement data. With the help of the EEPROM Electronically Erasable Programmable Read Only Memory storage unit on the board, it can be ensured that the sent data can be stored and that the data is not lost even in case of any power failure. The most important feature of the implemented system is that it can access the system through the Internet through the UDP protocol without the need for a computer or equipment to be able to send data to the panel. The completed work includes four parts Web server unit, Ethernet interface unit, control unit and led display unit.PIC18F4550 microcontroller is used in the control part and PIC16F887 microcontroller is used in the Ethernet interface part. The designed web server interface is written in C programming language in ASP.NET. In addition, serial Ethernet card, RS232 communication protocol and UDP communication protocol were used in the study.
