使用步进电机模拟电梯的电机。作如下设定：

（1）楼层为八层（地上7层、地下1层）；

（2）每层之间电机运转40圈；

（3）电机的转速设计为两种：

1）电梯的开始和末端的相对低速（电机转动的前5圈和后5圈）

2）运行期间的相对高速

（4）使用K1—K7分别模拟7—1楼层的呼叫开关，K0作地下层的呼叫开关；

（5）利用ＬＥＤ—ＬＥＤ0分别作７—１楼层及地下层的呼叫显示；

（6）ＬＥＤ数码管作电梯运行的楼层号显示；

（7）电梯的初始状态在１楼

-Stepper motor analog elevator motor. Set as follows: (1) Floor eight levels (7 levels above ground and one level underground)　(2) on each floor between the motor running 40 laps　(3) the speed of the motor design into two: 1) the beginning of the elevator during operation a relatively high speed (4) and the end of the relatively low speed (rotation of the motor 5 turns before and after 5 turns) 2) using the K1-K7 7-1 floors were simulated call switch, K0 for ground underlayer of the call switch　( 5) LED-LED0 to call for 7-1 floors and basement　(6) LED digital tube for elevator floor running No. 1　(7) the initial state of the elevator
