It uses Real Time Clock (DS1307) which work at the real time. The Arduino UNO is used to control all the functions; it gets the time through the keypad and stores it in its memory and display it on LCD display.

In this project, we are going to build a real-time clock circuit and connect to an arduino microcontroller. A real-time clock, or RTC, is an integrated circuit that keeps track of current time. It can keep track of seconds, minutes, hours, days, weeks, months, and years with leap yea...
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...
DS3231 Real Time Clock Programming Overview The first question that comes here is why we actually need a separate RTC for our Arduino Project when the Arduino itself has built-in timekeeper. Well the point is that the RTC module runs on a battery and can keep track of the time even if ...
From board design to prototypes to writing the library, it has involved a lot of my time but it's been a ton of fun through it all. I'm glad I'm seeing the light at the end of the tunnel, but there is still a healthy amount of work left. The final steps for this project are...
master 2Branches0Tags Code This project is a library for theArduinoplatform. It provides a simple interface to theMaxim DS1302timekeeping chip. It allows Arduino projects to keep accurate time easily. Features Of the features on the DS1302, this library provides support for: ...
This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather main board. This RTC is the most precise you can get in a small, low power package. Using our Feather ...
But the most efficient one is to use aWebSocket connectionto get the updated data in real-time. This method is not only efficient but saves up a lot of clock cycles for resource-heavy applications. In one of our previous articles, we have built such anESP32 based WebSocket serverthat...
Arduinolibrary for accessing the Microchip MCP7940 real time clock. There are two versions of the RTC, MCP7940M and MCP7940N, which differ only in that the MCP7940N has a battery backup supply pin and keeps the clock running on power failure. The MCP7940N also has additional registers whi...
