This paper presents the design and construction of a 300-member electronic voting system developed as part of an undergraduate project in 2010, with a case study of the 6th National Assembly of the Federal Republic of Nigeria. The system was implemented using the AT89S52 microcontroller, aimed at providing a secure, efficient, and reliable voting process for legislative settings. Manual voting procedures in assemblies are often hindered by delays, counting errors, and potential manipulation. This work responds to those challenges by designing an electronic platform where each of the members 300 can cast votes electronically, with the AT89S52 handling processing, validation, and storage. Principles of voting theory, including majority rule and proportional representation, informed the design. Testing confirmed improvements in speed, accuracy, and transparency compared to manual methods. While developed as a prototype, the system demonstrates the potential of microcontroller-based voting solutions to strengthen democratic governance, particularly in parliamentary and institutional contexts.
