1、 全自动洗衣机课程设计基于 51 单片机， C 语言实现。基本要求模拟全自动洗衣机工作过程。以电机替代洗衣机电机。显示洗衣机工作的状态（进水、浸泡、洗衣、脱水、结束） 。显示工作剩余时间（洗衣程序可自定义，时间精度：秒） 。洗衣时交替正、反转。扩展要求洗衣和脱水时电机转速不同。增加水位传感器输入。故障报警。增加声音提示。其它自定义功能。设计用 Preteus 仿真：仿真图如下：C 文件函数代码：#include/*/#define uchar unsigned char#define uint unsigned int/*/*/sbit mo_r = P32; /电机右控制线sbit mo_l
