Description
ABSTRACT
With the advent of technology, most tasks undertaken by man have now been overtaken by semi-conductor devices applicable in the areas of communication industry.
In industrial, commercial and recreational establishment, there is always the need to reach the public. The faster this is done, the better.
In this project: design and construction of an Electronic Bill Board (EBB), which is a display device that converts electrical signals transmitted from electronic devices into optical signals using Light Emitting Diodes (LEDs).
The EBB saves time, gives better visual effects and attraction, where it is used in adverts and other forms of attractive and urgent information dissemination.
