When power is reconnected, it displays the real time irespective to the time and duration it was in off state. I have a RTC module DS1307 (MR005-001. The DS1307 RTC is used as a real time clock chip which keeps the time running even if the main power supply is off (with the help of a battery), time and date are displayed on the SSD1306 128×64 OLED. First, you have to go to this link where you will find the DS3231 library in GitHub. DS1307 is called the Maxim-Dallas module for Arduino with which it allows us to have a precise system clock. These devices are cheap, have good accuracy and keep counting time even when the main MCU is not powered. There are different kinds of RTC modules available in the market. We will get the time and date from the RTC module using the library functions and then we will compare this time with the alarm time that we have set in the code. A rechargeable lithium cell LR2032 can be installed to keep the correct time also when the power supply is disconnected. In order to solve this time accuracy problem, we came up with the simple project Arduino NTP Clock using NodeMCU and DS3231 which update time of RTC module from NTP server. 02inchNote:Without battery. It is possible to force the system to use only the RTC for time keeping ( config ). Arduino is really powerful and we can make a real-time clock, but the problem comes in when the Arduino is turned off, or the power is disconnected, the time and date information is completely lost.
