如图连接电路后,编写程序实现将RTC模块进行当前时间设置。 这里我们直接调用了DS1307RTC.h这个库文件里面的例子实现校准时间的功能。 #include < Wire.h >#include < TimeLib.h >#include < DS1307RTC.h >constchar*monthName[12] = { "Jan", "Feb", "Mar", "Apr", "May", "
RTC.set(DS1307_HR, rr[4]); RTC.set(DS1307_DOW, rr[3]); RTC.set(DS1307_DATE, rr[2]); RTC.set(DS1307_MTH, rr[1]); RTC.set(DS1307_YR, rr[ } 结果 疑难解答 电脑时间实时更新 更多问题及有趣的应用,请访问论坛 更多 Real Time Clock Module (DS1307) V1.0 Arduino Library Schematic...
This post is about how to use the DS1307 Real Time Clock (RTC) module with the Arduino. You can also follow this guide for other similar modules like the DS3231 RTC. Introducing the Real Time Clock module The real time clock module is the one in the figure below (front and back view...

Arduino Digital Clock using DS3231 Pi Module circuit diagram So, connect the SDA or D pin of your RTC module to the SDA pin and the SCL or C pin to the SCL pin of your Arduino board. The Vcc pin of the RTC module can be connected to either +5V or +3.3V of your Arduino and th...

Sooner or later, the Arduino starts to feel a little claustrophobic. Your sketches start running out of memory, so you need more RAM. You want to talk serial to another peripheral (like an RFID Module) AND watch the action in the Serial Monitor at the sa
