采用步进电机模拟洗衣机电机,实现上水、浸泡、洗涤、漂洗、甩干等过程。洗涤分弱洗、轻洗、强洗;可设定3级水位设定,每级水位均设定水位下限(值自定);可选择漂洗次数(3~5次)。使用键盘进行流程及参数设定及自动存储流程,设定暂停键,可暂时停止洗衣机的工作,恢复后按原设定程序继续进行,同时设定停止键,可终止洗衣机的工作,并在LED或LCD上显示当前流程。-Simulation using stepper motors washing machine motor to achieve Sheung Shui, soaking, washing, rinsing, drying and other processes. Washing sub-weak wash, light wash, strong wash can be set to three water level settings, set the water level in each grade level were lower (the value of self-set) optional rinsing times (3 ~ 5 times). Using the keyboard processes and parameter settings and automatic memory processes, set pause button to temporarily suspend the work of washing machines and restore original settings after the process to continue at the same time set the stop button, may terminate the work of washing machines, and LED or the LCD displays the current process.

/* 程序详细功能介绍:
* 用AT89S51单片机产生“嘀、嘀、…”报警声从P3.2端口输出,产生频率为1KHz,
* 1KHZ方波从P3.2输出0.2秒,接着0.2秒从P3.2输出电平信号,如此循环下去,就形成我们所需的报警声了。
*
* 程序设计方法
*(1.生活中我们常常到各种各样的报警声,例如“嘀、嘀、…”就是常见的一种声音报警声,
* 但对于这种报警声,嘀0.2秒钟,然后断0.2秒钟,如此循环下去,假设嘀声的频率为1KHz,
* 由于要产生上面的信号,我们把上面的信号分成两部分,一部分为1KHZ方波,
* 占用时间为0.2秒;另一部分为电平,也是占用0.2秒;因此,我们利用单片机的定时/计数器T0作为定时,
* 可以定时0.2秒;同时,也要用单片机产生1KHZ的方波,对于1KHZ的方波信号周期为1ms,
* 高电平占用0.5ms,低电平占用0.5ms,因此也采用定时器T0来完成0.5ms的定时;
* 最后,可以选定定时/计数器T0的定时时间为0.5ms,而要定时0.2秒则是0.5ms的400倍,
* 也就是说以0.5ms定时400次就达到0.2秒的定时时间了。
