1602LCD液晶+DS18B20實現(xiàn)數(shù)字電子鐘
加入技術(shù)交流群
液晶顯示內(nèi)容： 2012-02-02 14C //第1行
00:20:38 Thurs //第2行
這個時鐘表 既可以顯示溫度，又可以顯示 當前日期是星期幾了。 這個星期幾的判斷方法就是根據(jù)一個 國際日歷公式來實現(xiàn)的。
實現(xiàn)功能：
1. 調(diào)整 年月日 時分
2. 顯示 當前周圍溫度
3. 顯示 當前日期的 是星期幾
4. 整點報時
5. 若調(diào)整時間 不合理， 比如2012-02-34 ，則 調(diào)整失效
6. 若調(diào)整時間，則可以放棄所調(diào)整的時候。
