THE DESIGN AND IMPLEMENTATION OF ELECTRONICS SEQUENTIAL SIGN PATTER DISPLAY

ABSTRACT
This design implementation of this electronic sequential sign post display employs the use of some specialized components. This section of the project introduces the reader to the different section of the project and the components that makes them up.Emphasis are laid on describing the behaviour and operational system of the components as related to the project modeling, analysis, design and implementation of an ELECTRONIC SIGN POST, which is made up of a power supply, a shift register, a counter, multivibrator (555CMOSI.C) transistor, relay, resistors of different ohmic values capacitors, sensitive mic (for the switching system) and 220V AC lamp.
