小項目實踐：單片機做的半導體制冷小冰箱 原理圖和程序

最近天氣比較炎熱閒來無事，自己在家DIY了一個小冰箱，試了一下製冷效果還可以的，下面就把製作步驟和技術資料和大家共享一下：

這個冰冰可樂什麼的真的太適合不過了。。器材：一個電源模塊，220v轉12v，6A。以及一個封裝好的製冷器，元件清單都在原理圖上可以看出來，繼電器用的是繼電器模塊。

防水型的18B20，繼電器模塊，12c887時間芯片，12864液晶屏，蜂鳴器，89c58單片機芯片，接線子，什麼開關，按鍵，電阻電容的你也應該知道的，就是一個單片機模塊。。這些就是控制板的元件了，然後你還要去淘寶上買製冷器和製冷器血藥的配套的電源模塊。。然後你就可以自己DAY一個小冰箱了。。

廢話不多說先上圖：
這是系統控制板子需要自己DIY的板子散件，待焊接

焊接好的系統控制板成品

連接好的待測試品

接上顯示LCD後可以顯示的功能
