    【自造學堂】如何用Arduino x RTC完成LCD時間顯示?
    *0*RTC(即時時鐘)模組*0* 如何更新 DS3231 RTC 模組的時間與大型數字時鐘製作

    需要安裝資料庫
    for DS3231
    (下載後解壓縮安裝)  DS3231_TEST

    for 0.96OLED
    (資料庫搜尋安裝)      Adafruit_GFX
    (資料庫搜尋安裝)      Adafruit_SSD1306

    for I2C LCD
    (資料庫搜尋安裝)      LiquidCrystal_I2C

    額外經驗
    如何把1變成01(補0)
    C語言Printf 自動補0
