Rhushiraj D. Mahalle | S. A. Bhosale 
Abstract: now a day the notice boards are the primary things. At institution or organization or in the public places just like the bus stops, railway stations or parks notice boards are there. But sending several notices day to day is a very difficult task. The purpose of the proposed system is to display the message on a matrix display send by the user. The system consists of transmitter at user side and receiver connected to the display. It totally based on real time i. e. no need to store the instruction in the database. Its operation is based on microcontroller ATMEGA64 programmed in assembly language. When user sends message it receives at receiver and for that wireless communication nRF24L01+ can be used. Also it contains a LM35 temperature sensor to show the nearby temperature, humidity sensor to show the presence of water in the air and most important GPS clock. The date and time is directly display on the notice board with the help of Global Positioning System (GPS), no need to set date and the time every time.
