Design and Implementation of a Trainer Board for Digital Logic Design Principles Lab

Educational institutions suffer from a scarcity of practical training due to the financial constraints imposed by the US sanctions on our country, Sudan, for more than three decades. Despite the availability and diversity of equipment and tools for practical educational applications on the global market, the economic reality of Sudanese educational institutions allows only training at the basic level in most cases. Our situation in the Digital Electronics Lab at Nile Valley University is similar to that of everyone else under the US sanctions situation. We used to train students on the basics with very simple equipment. We are barely able to implement 25% of the practical material covered in the course. This is because we use simple electronic components to implement the exercises, which complicates the application, consumes materials and effort, and takes a long time per the student. Through this paper, we aim to utilize the simple capabilities available in our lab and the local market to design and implement a laboratory board that isolates students from interacting with basic electronic components and enables them to directly apply digital logic. They then obtain the results of the exercise, enabling them to write the exercise report and achieve the desired objectives of the experiment. We also hope that the designed board will improve the achievement rate and raise up the percentage of practical work applied in the laboratory according to the course plan.
