ABSTRACT

Electronic Digital message display Board is an electronic gadget that is capable of displaying length of alphanumeric characters, symbols and any form of representation on a matrix of light emitting diodes (LED) scrolling the characters across the screen for information disemination. This project set out to solve the problem of inadequate clarity, objectiveness and degree of comprehension inherent in paper bill boards. Also, response to the information is further enhanced when the medium employed is attractive and highly inviting, as the case is for a moving display. The design and construction of the electronic digital display board consist of some units that make up the whole hardware. Among the unit are: Input unit, Controller unit, Display unit and power supply unit as well as the decoder unit. There are some basic electronic components that were used during the construction, These involves the following: PIC16F877A microcontroller, resistors, capacitors, voltage regulator, crystal oscillator, LEDs, transformer, relays, bridge rectifier, and transistors. The drivers unit consists of NPN transistors and 1k resistors thereby, serving as drivers that drive the data which has been transformed to different patterns of  display from the data bus of the chips to the display unit (LED). The project here was tested at various stages to ascertain its workability.
