PROJECT DESCRIPTION

The intention of this project is to display  a notice in a scrolling format on the alphanumeric LED display based on the program in the microcontroller that makes the characters move in an attractive manner.This type of scrolling system is applicable in public areas, on transport vehicles, advertisements, railway platforms, banks, hotels, nightclubs, etc.

The proposed system uses a microcontroller of the 8051 family and a rectified-power supply. The message is selected by the user through slide switches which are interfaced to the microcontroller. A set of 16- numeric LED displays are connected to the microcontroller with the help of  decoder for displaying all 16 characters at a time.

When a switch is activated, the corresponding message is displayed by the microcontroller according to the signal assigned to a particular switch. 

This particular project in future could be implemented by interfacing it with a GSM modem. A user can send the message to the control unit via SMS and the data gets displayed.
