基于C51单片机计时器
有电子秒表功能，LED键盘自检等程序；1）上电启动后，时钟计时，显示器显示00:00，并开始计时，每过1秒加1，直至59:59，再加1回到00:00，循环一次是60分钟，计时结束后蜂鸣器响一声报警提示。
2）按下K1键后，选择秒表计时，显示器显示00:00,每过1秒加1，直至59:59，再加一回到00:00，循环一次是60分钟。此秒表计时过程中需要暂停/继续功能时，按下k2键实现，按下k3键实现复位功能并且回到时钟计时，计时结束后蜂鸣器响一声报警提示。
3）再次按下k1键，选择倒计时，显示器显示59秒，每过1秒减1，直至00:00，计时停止，蜂鸣器响一声报警提示，此倒向计时过程中需要暂停/继续功能时，按下k2键实现，按下k3键实现复位功能并且回到时钟计时。按下k4键，倒计时置位，显示器显示59秒。
