2021年12月29日 | 单片机做的半导体智能制冷小冰箱

前几天一个朋友对我说，马上要过年了

准备买点年货放冰箱，正好我最近不太忙，便想着做一个小冰箱玩玩

废话不多说，先介绍器材

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。。

先上实物图，整个过程需要自己亲力亲为，虽然有点麻烦，但是里面还是有很大乐趣的

这是控制系统板子散件

焊接好的控制板

连接好的整个系统

下图这些显示都是可以实现的功能。。

这是一个定时关闭的功能

时间设置及其他功能

最低温度你们看吧！这个小冰箱实际测试结果我还是挺满意的，可以喝冰镇啤酒饮料，这几实验基本成功。

搭的系统有点丑，我下次有时间再改进一下，因为都是模块搭的，所以就不过多啰嗦了，
