1、用一个单片机和DA转换组成一个随机电压发生单元（0~5V）；
2、另一个单片机和AD转换组成数据采集单元；
3、通过串行接口将采集的数据传到上位机中，需要编写上位计算机程序，对采集的数据进行处理，如显示当前值、画出一定时间内的记录曲线等。(1. A random voltage generating unit (0~5V) is composed of a single chip microcomputer and a DA converter;
2, another single chip microcomputer and AD conversion constitute data acquisition unit;
3, the data will be collected through the serial interface to the computer, need to write computer programs, processing the collected data, such as the display of the current value, draw the recording curve within a certain period of time.)
