This system can meet the countdown display the remaining time of a single game to pause, to show both sides scoring key input to modify the score, if an error scores can be modified accordingly. The end of the game, a voice prompt. The system meets the requirements for the work of the general basketball timer. Digital display, micro-power, small size, the use of flexible and many other advantages to be more widely used in pocket-sized instrument and low-power applications, but also conducive to the success of the hardware in kind. The main method of design is to determine the feasibility of the program through the simulation, and then meet in kind during the local test simulation design requirements, the overall circuit structures to complete the final testing and debugging.
