Design and implementation of a microcontroller based printed circuit scrolling message notification board

Abstract

The noticeboard is an essential thing in any establishment or association to convey data among the partners. In the occupied and quick-moving present reality, the traditional paper notice framework is tedious and not reasonable for brisk sharing of data. This exploration work aimed at designing an electronic scrolling display board on a specially designed Printed Circuit Board (PCB). The thought behind this undertaking is to furnish its clients with a basic, quick what’s more, dependable approach to set up a significant notification in a LED where the client can display messages to be shown directly on the LED unit from a computer to the microcontroller and also to give notification about anything at a particular moment to the targeted group or audience. This will significantly provide improved measures to the limitations and restrictions of conventional notice boards. The system is created with an ATmega 328P microcontroller from Atmel. The microcontroller showed all the usefulness of the showcase notifications required. The Display is acquired on a 2X (16X72) dot matrix display board, orchestrated on a cascaded specialized PCB designed with a Ki-cad schematic/design software suite for a wider view. An ideal instant message from a computer is sent utilizing Arduino IDE and HT1632 driver IC to drive these tremendous LEDs. The framework was tried to work as per the test message. This brilliant notification board can make the notification arrangement of an association much basic, quick and financially savvy and provide a limitation to an accident that can occur when sticking paper-based notification sheets.
