模拟电压采集，直流电机控制

基本任务：

1、对模拟电压进行采集转换为数字信号，并实时显示。

2、用转换的到的数字信号再经数模转换，对直流电机进行控制。

拓展任务：

1、通过发光二极管作为信号指示灯，实时的指示直流电机的工作状态是否正常。

2、建立报警电路，对电机非正常工作情况下进行报警

-Analog voltage acquisition, DC motor control.

Basic tasks:

1, the analog voltage is converted to a digital signal acquisition and real-time display.

2, with the conversion to a digital signal and then the digital-analog converter, DC motor control.

Expanding tasks:

1, by the light emitting diode as a signal indicator, real-time job status indicator DC motor is normal.

2, the establishment of the alarm circuit of the motor non-normal operating conditions alarm
