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. This project deals with an advanced wireless notice board.

The main objective of this project is to develop a wireless notice board that displays messages sent from the user’s mobile. When a user sends a message from his mobile phone, it is received by a SIM loaded GSM modem at the receiver unit.

The GSM modem is duly interfaced through level shifter IC for establishing RS232 communication protocol to the microcontroller. The message so received is thus sent to the microcontroller that further displays it on electronic notice board which is equipped with a LCD display interfaced to a microcontroller from 8051 family duly powered by a regulated power supply from mains supply of 230 volt ac.

Further development to this project can be done by providing message storage facility by non-volatile memory i.e. EEPROM attached to the microcontroller for retrieval of old messages if required. It can also be expanded to a bigger LCD screen.

Feature - Missed Call Saving in GSM.
Multiple User Message Display.

I got to know about Edgefx through Internet when I was searching for Electrical projects. I decided to buy my project as I was getting all the components along with the guidance on how to the project. I liked the report provided along with the kit.Edgefx Team is quite polite. I would like to name Mr. Samadhan and Ms Raji who guided me with my project.I would like to recommend to others because of the service provided by Edgefx. Please update basic information in website e.g. brief circuit description, basic theory about any project.
