Multiuser SMS Based Wireless Electronic Notice Board Project represents the model to show the notices on technological notice board in colleges through sending messages in the form of SMS by mobile.
The hardware includes microcontroller AT89s52, the microcontroller is blend with converter MAX232 level and GSM Modem. The hardware also includes 64K EEPROM chip AT24C64 and includes the actual time clock DS1307 to sustain the time track. The LED display is connected to microcontroller to display notifications.
Microcontroller coding would be accomplished with the help of Keil and Embedded C. Many customers are authenticated to update the notices over the technological notice board by giving password with the help of wireless communication.
