/* 程序详细功能介绍：
*当按下按键P3.3 ，AT89S51单片机产生“叮咚”声从P3.2端口输出
*程序设计方法
* 1． 我们用单片机实定时/计数器T0来产生700HZ和500HZ的频率，根据定时/计数器T0，我们取定时250us，
* 因此，700HZ的频率要经过3次250us的定时，而500HZ的频率要经过4次250us的定时。
* 2． 在设计过程，只有当按下SP1之后，才启动T0开始工作，当T0工作完毕，回到最初状态。
* 3． “叮”和“咚”声音各占用0.5秒，因此定时/计数器T0要完成0.5秒的定时，对于以250us为基准定时2000次才可以。

这是参加电子设计大赛时的作品：红外遥控小车：用红外线通过一块AT89S52单片机发射信号即编码，并用红外接收头接收信号；接着再用另一块AT89S52单片机对红外发射出的信号编码进行解码，最后再用一块AT89S52单片机用解码所得码值编写程序后驱动步进电机。步进机功能启动后不仅能使受控小车向前后左右四个方向前进和转弯，而且还能控制小车再地上转动并留下方形或圆形等形状。-This is the time to participate in Electronic Design Contest works: infrared remote control car: Using infrared transmission signal through an AT89S52 microcontroller that is encoded and used infrared receiver to receive the first signal and then using the other an infrared emitting MCU AT89S52 code and decode the signal and finally an AT89S52 microcontroller then proceeds with the decoding key value of the preparation of procedures to drive a stepper motor. Stepper machine function activated not only make the car forward in a controlled direction and after about four turns, but also to control the car and then turned and left the ground such as square or round shapes.
