功能简介：

该实验使用ADC0832芯片的通道0测量实验板上一个电位器提供的电压值。下载好程序后，转动电位器即可观察到显示的电压发生变化。

注意调节程序中的choose=0，选择右边电位器输入；choose=1，选择左边电位器输入，

本程序是：choose=0，选择右边电位器输入，可以用电压表查看输入值与显示数字比较，看是否相等，-Features:

　　 The experimental use of an experimental measurement of an external voltage experimental procedures. Download a good program, an external voltage is connected to the ADC IN pin No. 2, the digital display on an external voltage is the voltage of the current value. External voltage should be between 0 ~ 5V, burn ADC0832 chips over the General Assembly, be sure to note
