Abstract: This article designs a system of basketball game timekeeping and scoring, which is based on the single-chip microcomputer. The system mainly through the single-chip microcomputer AT89C51 chips as the core control elements, using 1602 LCD monitor as a displaying component, the keyboard input circuit and alarm prompt circuit component.The hardware circuit design with software programmer debugging make up the system of basketball timing and scoring, which can be used in a basketball game. In a basketball game, this system can show the remaining time in a period, and also be suspended and display the scores of both sides, if there and mistake, the scores can be need through key inputting. When controlling the ball for more than 24 seconds and the game ends, the system is able to prompt by voice. So the system can be used as a common basketball game timer. Basketball game timing and scoring device because of its low power consumption, small volume, use agile, easy to carry and other characteristics, it easy to promote in colleges and have a good market prospect.

Keywords: ATS89C51; LCD1602; Counter; Timer
