小项目实践：单片机做的半导体制冷小冰箱 原理图和程序

最近天气比较炎热闲来无事，自己在家DIY了一个小冰箱，试了一下制冷效果还可以的，下面就把制作步骤和技术资料和大家共享一下：

这个冰冰可乐什么的真的太适合不过了。。器材：一个电源模块，220v转12v，6A。以及一个封装好的制冷器，元件清单都在原理图上可以看出来，继电器用的是继电器模块。

防水型的18B20，继电器模块，12c887时间芯片，12864液晶屏，蜂鸣器，89c58单片机芯片，接线子，什么开关，按键，电阻电容的你也应该知道的，就是一个单片机模块。。这些就是控制板的元件了，然后你还要去淘宝上买制冷器和制冷器血药的配套的电源模块。。然后你就可以自己DAY一个小冰箱了。。

废话不多说先上图： 这是系统控制板子需要自己DIY的板子散件，待焊接

焊接好的系统控制板成品 连接好的待测试品 接上显示LCD后可以显示的功能 系统完整演示图 智能小冰箱的C语言参考源代码：
