ABSTRACT

Advancement in the technology of optoelectronics information presentation has helped to shape the way information has been and is being delivered in recent times. Traditional means of conveying information such as billboards, paper prints in academic institutions may not be ideal with the advancements in technology. Most institutions of higher learning still display their class schedules on paper prints on large notice boards, and class schedules are still pasted on the walls of classrooms which can be damaged easily. The students need to be reminded which course they are to have at intervals. The knowledge of optoelectronics, computer programming languages, and wireless communication protocol was leveraged to create a microcontroller system capable of displaying class schedules on light emitting diodes connected in arrays. The system’s frame work was first drafted, to give a broad view of the system This was followed by a structural decomposition of the system which broke the entirety of the system into sub functional units. The wireless communication module relied majorly on baud rate for serial communication. A sending data using the android device using a wrong baud rate created invalid characters when sent to the display board.
