Wireless Smart Notice Board Using Dot Matrix

Abstract

Abstract: Whether a firm is for profit or not, the information sharing component of information technology is a major factor in all types of businesses. Nowadays, all company models depend on and use the capacity of advertising to market their goods and services. The present demand of the modern business and information world is for digital advertising. International airports, metro train stations, shopping centres, bus stops, etc. all employ scrolling LED dot matrix displays. Led displays are a good way to show information, but making the message dynamic is challenging since users must adjust the message content to meet their particular needs. The user must connect the Led display to the computer in order to change the message content. The wireless based dot matrix display creates the wireless connection between individual mobile and Led display in the event that the user requires pairing the Led display with the computer in order to change the message content, which makes it difficult to place the display board anywhere due to the dedicated and complex setting up pattern. It provides the facility of real time message displaying means the user can change the message content that is to be display. The message is sent from a mobile device to the LED display, and the microcontroller handles all processing for scrolling the message's content on the LED display. The project's goal is to create a wireless scrolling message board that allows the user to update the information without using a connection to connect the display board to a computer or laptop. The user has the option of using Bluetooth or Wi-Fi to refresh the message content.
