ABSTRACT

This report is aimed at explaining the Design and Construction of electronic message display board. It enumerate why we need electronic scrolling message display which is primarily for passage of information across the staff, students and public. It also includes the aim and objectives, advantages and disadvantages with a well narrated literature review and timeline that relates to digital display and its current trends in digital world.

Adequate coverage was given to mode of operation, result and discussion on the project work including Conclusion, Recommendations for further study, Bill of Engineering Measurement and Evaluation (BEME) and Reference.
