Abstract
The main objective of this work is to develop a notice board system using an Arduino board with Wi-Fi being remotely controlled by any Android OS smart phone. As technology is advancing so information is also getting smarter and scrolling. Modern information is gradually shifting from conventional notice board to centralized control system, involving Wi-Fi system. Presently, conventional notice board located in different location makes it difficult for the user to go near them to operate. In this system we are using Arduino master as main controller and remaining four Arduino as slave. When information is given through Wi-Fi master Arduino takes receives data from wi-fi according to coding it feds to slave Arduino and display on LED notice board at same time information gradually shifting with controlled by shift register. With help of shift register data moving from one location to next location like this gradually scrolling. In system all slave lines are displaying different data with scrolling received from master.
