A Survey on Smart Messenger Notification Board
Notice Boards are a common occurrence in institutions or organizations which occurs on a daily basis. Notice board is primary thing in any institution or organization or public places like bus stops, railway stations or parks etc. Current notice boards are updated manually which cause waste of resources like paper, printer ink, man power and also brings about loss of time.Some of the schools and colleges are using programmable digital notice boards that require enough time and man power to change the notices every time as these boards need to be reprogrammed each time. This makes them inefficient for immediate information transfer. In this paper we have proposed a system which will enable people to wirelessly transmit notices on a notice board using arduino. In this system only authorized people can give the notices. We can also make the system compatible with more than one wireless technology. In this paper, we have designed a smart notice board by which we can update the notice to be displayed from any part of the world in no time and it is advantageous during emergencies when we want to display alert messages or changed schedule speedily.
