ABSTRACT
To address the problem of timing in our secondary schools, we present a design, simulation and implementation of an enhanced timing system for academic purposes. The system involves the design of a digital stopwatch for Ditsweletse Community Junior Secondary School in Botswana to be used in timing examinations and tests, laboratory experiments to enhance national and international competitiveness among students and promote scientific analysis for students. The system is divided into five major blocks that house different circuits and combined to perform the function of an enhanced digital stop watch. This division includes; Power supply, timing circuit, counter circuit, decoder, and display circuits. The system was designed and simulated using Proteus 8, a circuit building software used for building electronics system. The system was simulated, and simulation results were in accordance to the design specifications.
