DEVELOPMENT OF MICROCONTROLLER BASED SCROLLING MESSAGE LED DISPLAY SYSTEM
Abstract
Electronic digital display system is very efficient and cost effective way to spread
messages to thousands of people. This is contrast to traditional nonelectric signs where
static information is displayed by physically applied message to the sign surface by
printing or painting. P10 (32x16 LED dot matrix display module), wireless P10 LED
Matrix Controller, Arduino and 74LSS95 shift register are used to build an electronic
display system by connecting all the anodes in P10 module to the microcontroller and
the columns are connected to shift register (74LS595). Arduino microcontroller was
program for LED Display using different Text messages at varies scrolling speed. The
developed information LED display system was tested satisfactorily.
Although cost of the developed system is expensive but it is durable and customizable,
like the text messages can be changed easily whenever needed and it will be used as
Digital Notice Board.
