51小车程序运行效果：将小车置于一个桌面上(桌面请不要使用黑色)。打开电源的开关，小车开始前进运行，同时运行指示灯闪亮，这时如果前方有障碍物(或走到悬崖处)，小车将会先进行后退一段时间，并有蜂鸣器报警，再向左转一段时间，最后开始向前运行、左转、后退、右转、可以通过前方指示灯来观察。这时你可以能过声控(如拍手声)来让小车停止和开启.同时你也可以用遥控来控制小车的运行。按“1”，小车将向前运行，按“2”小车将后退，按“3”小车将左转,按“4”小车将右转.按其它(0-9)键，小车数管码显示相应的数字符号。按电源键，小车将会停止运行。同也可以用电脑将小车发送数字信号。其数码管也将显示相应的数字(0-9)。并执行相应的功能。当然S1、S2 也是起作用，分别用于控制小车的停止和开启。(注意：操作时应在小车前进时操作，后退、左转、右转等操作时，没有写相应的查询程序)-Effect of the running procedures 51 car: place car on a desktop (desktop do not use black).
