DESIGN AND CONSTRUCTION OF "FEDERAL UNIVERSITY OF TECHNOLOGY MINNA" LIGHT SEQUENCER DISPLAY

Abstract

This project report presents the design and construction of a light sequencer display. Although, most practical light sequencer displays in use today consists of those controlled by an Electrically Erasable Programmable Read Only Memory (EEPROM). The EEPROM is programmed by a programmer in such a way that the visual display will light in the order in which it was programmed in the EEPROM. Although, we also have other more sophisticated visual displays but, for the purpose of this project a shift register (74LS 164) was used to display our output sequentially using light emitting diodes (LEDS) in place of the more sophisticated and expensive EEPROM. The shift register (74LS 164) shifts the output in a serial-in-parallel-out (SIPO) mode, in order to display our characters both in the sequential and group modes.
