The coal gas reports to the police the system publishes, scribing the electronics measure the instrument walked into the arithmetic figure turns the ;"。With the rapid development of electronic technology, especially the emergence of large-scale integrated circuits, fundamental changes have been brought to human life. The release of the gas alarm system and the engraving of electronic measuring instruments have entered the calculation of the abacus. In basketball games, accurate timing and scoring are important guarantees for ensuring the fairness of the game. Traditional manual scoring methods often have problems such as inaccurate scoring and timing errors. Therefore, designing an intelligent timer and scorer has important practical significance. This paper details the hardware and software design process of the basketball game timer and scorer, using a single-chip microcomputer to complete the timing and scoring functions, and realize the functions of score modification and accurate time display. With this device, the problem of inaccurate scoring and timing in basketball games can be effectively solved, improving the fairness and accuracy of the game. Keywords: Single-chip microcomputer, basketball game, timer and scorer, hardware design, software design.
