伟福LAB2000单片机仿真系统直流电机控制:利用实验仪上的D/A变换电路,输出-8V至+8V电压,控制直流电机。改变输出电.压值,改变电机转速,用8255 的PB.0 读回脉冲计数,计算电机转速。在电压允许范围内,直流电机的转速随着电压的升高而加快,若加上的电压为负电压,则电机会反向旋转。本实验仪的D/A变换可输出-8V到+8V的电压,将电压经驱动后加在直流电机上,使其运转。通过单片机输出数据到D/A变换电路,控制电压的高低和正负,观察电机的旋转情况。
在电机转盘上安装一个小磁芯,用霍尔元件感应电机转速,用单片机控制8255读回感应脉冲,从而测算出电机的转速。

(1) 有一个主持人控制开关和8路抢答按扭,当主持人允许抢答时才能进行抢答操作,并用一个数码管显示抢答选手的号码,同时其他选手不能再抢答。
(2)电路上要加个蜂鸣器的电路,当有选手抢答时蜂鸣器响一下。
(3)要有倒计时功能,开始抢答时开始倒20秒计时,用两个数码管显示,当有人抢答时停止倒计时。
2.2拓展部分
用按键可设置倒计时的时间,范围在5秒到30秒之间。-(1) has a host switch and 8-way control button to answer in, when the moderator allowed to be carried out to answer in time to answer in operation, and use an LED display to answer in the number of players, while other players can no longer answer in his place. (2) the circuit, we should add a buzzer circuit, when there are players when the buzzer rang to answer in about. (3) to have the countdown feature to begin to answer in 20 seconds when you start down time, using two digital tube display, when someone stops to answer in the countdown. 2.2 The expansion of part of the buttons can be set with the countdown time, the range of 5 seconds to 30 seconds.
