In this project, we will be interfacing the RTC DS3231 with Arduino to create a real-time clock system. The RTC (Real-Time Clock) is a crucial com
ponent in many projects, as it provides the necessary time and date information. The DS3231 is an accurate and reliable RTC module that can maintain timekeeping with a battery backup.
To begin the project, we will first connect the DS3231 to the Arduino using the I2C protocol. The DS3231 communicates with the Arduino through the I2C bus, which requires only two pins for data transfer. We will use the Arduino Wire library to communicate with the DS3231 module.
Overall, interfacing the RTC DS3231 with Arduino is a straightforward process that can be accomplished with minimal effort. This project is an excellent introduction to working with the I2C protocol and demonstrates the importance of accurate timekeeping in various applications. With the DS3231 RTC module and Arduino, you can create a reliable and precise real-time clock system for your project.

Which IC did you use for time and date? Did you use any battery to timing IC?

[@circuitcraft9203]

It is RTC DS3231, yes it uses a cell to keep track of time even when not connected or arduino is powered off.

The push switch is of how many pins?

[@circuitcraft9203]

It is of two pins

[@ianhesm8815]

I hope you will reply Sir.

Hi

[@rakshaghotekar5661]

what is that beside resistor

[@circuitcraft9203]

It is a push button

[@anegg2090]

Im still confused on why is it converted to decimal can you explain?

[@circuitcraft9203]

It is because data that I am getting is in BCD i-e 4 bits to represent each number from 0 to 9 then if I have to write 12 in BCD it will be written in bits as 0001 0010 that is why I needed to convert it to decimal

@@circuitcraft9203 ahhh ok, tysm man

[@eunsung7712]

The code does not work. Help!

[@circuitcraft9203]

Ok I need to know these things.
Is real time clock DS3231 ? And LCD is with I2C module which has only 4 connections ?
