DS1307 Arduino Mega2560
How to Access the DS1307 RTC Module Using Arduino Mega2560? – In the previous tutorial, I made a tutorial on How to Use the RTC DS1307 Arduino Using the Adafruit Library. Now I will share how the RTC DS1307 can be accessed using Arduino Mega2560.
I had a slight problem when the module was accessed using the Arduino Mega2560 with the same circuit using the Arduino Uno, namely not succeeding in reading data from the RTC.
So, the solution to this problem is to add a Pull-Up resistor on the SCL and SDA pins. To find out the best pull-up resistance value, please read the article on how the I2C protocol works.

To be able to communicate between RTC and Arduino, we need to connect them with I2C communication, SDA to SDA, and SCL to SCL. The network is as follows:
In the RTC module circuit above, there are two pin sides (VCC, GND, SDA, and SCl) on the left and right. Friends, you can use one of them, left can be right too because they are connected to each other.
In order to communicate between I2C, we only need 2 conditions, namely SDA and SCL. In order to determine which IC to use, we must know the I2C address of the IC.
How to Use RTC
Now, we will try to read data from RTC. The data taken is day, date, month, year, hour, minute and second, read more in Build an RTC Arduino ESP (DS1307 & DS3231).
That’s the tutorial on how to access the RTC DS1307 Arduino, hopefully it’s useful for all of us. Thank you for visiting. If friends find it useful, please share it with other friends who need it.
