Arduino Based Electronic Notice Board and Home Appliances Control by Using Gsm Technology

Abstract

Notice boards plays a major  role in  Educational institutions  or any organisations or bus stations and railway stations the information can be shared by means of  messages. But sending various messages at a time becomes tedious process by using paper  notices . In order to overcome the difficulties we are introducing SMS based  notice board . This paper  deals with the SMS based  notice board  incorporating widely used GSM SIM900 for displaying messages via user’s mobile . The main idea behind this paper is to provide the simple and flexible way  for the user to display notices on the LED display through messages by using GSM SIM900. This GSM SIM 900 module will be used anywhere irrespective of the place where the network connectivity will be available.  In this paper  we are not only dealing with the SMS based notice board but also with the home appliances control with the help of ATmega 328 controller . With the help of this controller we are controlling home appliances like Fan and light with the help of the messages sent to GSM SIM900. The GSM SIM900 will receive the commands what we sent from the mobile and operation will perform accordingly.
