文档介绍：基于单片机的微波炉控制器
摘要
随着社会的快速发展,人们的生活节奏逐渐加快,微波炉方便快捷的烹饪特点为现代人的生活提供了便利,在现代家庭中,微波炉已成为必备的烹饪工具之一。
通过制作微波炉控制器,更充分了解微波炉的结构特点和工作原理。本文介绍了微波炉控制器的设计、调试与实现。本设计中的微波炉控制器以AT89C52单片机为核心,由矩阵键盘、时间显示、控制输出等模块组成。并且能够实现大、中、小火力选择以及启动、停止和时间重设功能。其中初始时间由矩阵键盘输入设置,火力大小通过发光二极管来表示、电机的转速表示在加热中。微波炉控制器工作时,将按照设定的时间进行加热并倒计时,等时间到后报警提示、火力指示灯熄灭、转盘停止运转。

Abstract
With the rapid development of our society and the gradually speeding steps of our life, the convenient and efficient cooking features of microwave oven have provided us great help and make it an indispensable cooking tool in our modern life.
Through the making of the microwave oven controller, I have a better understanding of its structural features and working principles. This article introduces the design, debugging and implementation of microwave oven controller. With the SCM AT89C52 at the core, it is made up of modules of matrix keyboard, time display and control outputs and etc. What’s more, you can choose a max, mid or min power and make it work or stop or even time resetting at your will. And the initial time is set by matrix keyboard; the power size is shown by light-emitting diodes; the spinning of the motor shows its working. When it works, it heats according to the setting time and countdowns until the alarming system ringing, the power indicator light packing up and the turntable stopping.
