基于Arduino的多功能數(shù)字時(shí)鐘

1、基于Arduino的多功能數(shù)字時(shí)鐘實(shí)現(xiàn)功能：顯示時(shí)間、日期和星期斷電保存時(shí)間通過按鈕設(shè)置時(shí)間、日期整點(diǎn)響鈴自定義鬧鐘顯示溫度自定義報(bào)警溫度按鍵功能：按選擇鍵進(jìn)入設(shè)置時(shí)間功能；同時(shí)按+-鍵進(jìn)入鬧鐘和報(bào)警溫度設(shè)置功能；再按選擇鍵光標(biāo)跳動(dòng)，光標(biāo)跳到哪當(dāng)前的參數(shù)即可通過加減鍵修改。實(shí)驗(yàn)所需器件：Arduino開發(fā)板或Atmega328P芯片、DS1302時(shí)鐘芯片、溫度傳感器DS18b20、蜂鳴器、不帶鎖開關(guān)、LCD1602、10K可調(diào)電阻、10K電阻（可不接，即DS18b20端口的電阻可去掉，不影響讀數(shù)）ProteusISIS仿真圖：BUZIERkTEXTaWF旳陽伽ChT忻poiyreifaMTiT
