IOT Based Digital Notice Board

In this proposed system the idea of IOT Based Web Controlled Digital Notice Board Using GSM Technology has been presented. So our main aim is to reduce paper work and time At present, when information has to be updated in a notice board, it has to be done manually. To change message on display, it needs to change microcontroller program code again. By adding web controlled IOT based communication interface to this system, we can make smart notice board to overcome these limitations. So we have interfaced with raspberry pi with WIFI module. Users can access to update notices on notice board by providing them password.
