SCL to the SCL (yellow wire on STEMMA QT version) i2c clock pin There are internal 10K pull-ups on the PCF8523 on SDA and SCL to the VCC voltage pcfmetro Fritzing Talking to the RTC The RTC is an i2c device, which means it uses 2 wires to to communicate. These two wires are us...
voidloop(){ displayTime();// display the real-time clock data on the Serial Monitor, delay(1000);// every second } 在实时时钟中保留时间 如果您不想在每次关闭 RTC 时重置时间,您应该执行以下操作: 已经有17人购买查看了此内容 50 登录注册 这是在 RTC 中设置时间的一个非常重要的步骤。如果您不...

In this part, I will roughly explain about how you can get started to have your own DIY digital clock! Step 1 The hardware that you need for this are : DS 1307 RTC IC x 1 –datasheet 32.768kHz Quartz Crystal X 1 Coin cell CR2032 & the holder ...
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...
SCL:It is the i2c clock pin - Which communicates with the RTC. SDA:It is the i2c data pin - Which communicates with the RTC. So now that the introductions are done lets get to actually making the module. The instructable has steps of the soldering and the places of the components in ...
步骤1. 下载RTC库。 步骤2.参考如何安装Arduino库来安装Arduino的库。 步骤3. 创建一个新的Arduino草图,并将以下代码粘贴到其中,或者通过路径直接打开代码:文件-> 示例 -> RTC -> SetTimeAndDisplay。#include <Wire.h>#include "DS1307.h"DS1307 clock;//define a object of DS1307 classvoid setup(){ ...
