Abstract: Notice boards are common in variety of institutions and are used daily. The urgent notices are normally printed on the papers and then displayed. The proposed system can announce a notice by just typing on a computer. If there is no notice, along with temperature and humidity, time will be displayed. ZigBee module is used for wireless communication. At receiver side, matrix of LEDs will display a notice which will be controlled by microcontroller. GPS module is to interface with microcontroller for displaying real time. At transmitter side, computer is used where ZigBee module will be interfaced via USB to serial converter. An application is developed to write a notice so that when anything is written on that window it will display immediately on the board. With the help of this application notice can be transmitted from any computer if needed.
