RTC Module DS1307 Arduino

RTC Module DS1307 Arduino - You could use this module in adding a clock on your Arduino system. This module enables the use of date & time within your system. You need a coin cell battery CR2032 for this one if you want it to keep the time even when your MCU is powered off. 

Frequently Asked Questions About RTC Module DS1307 Arduino

Q1: What specifically is an RTC module?

RTC is an abbreviation for Real-Time Clock. An RTC module is a hardware device that maintains the current time and date even when power is lost to the device to which it is connected.

Q2. What actually is the DS1307 RTC module?

The DS1307 RTC module is a well-known and reasonably priced RTC module that is frequently used with Arduino boards. It communicates with the Arduino using the I2C interface.

Q3: What are the primary characteristics of the DS1307 RTC module?

  • Real-time clock providing seconds, minutes, hours, day, date, month, and year information.
  • Battery backup for consistent timekeeping even when power is lost.
  • I2C interface for convenient communication with Arduino boards.

Q4: How can I attach the DS1307 RTC module to an Arduino board?

Using the I2C interface, the DS1307 RTC module may be attached to an Arduino board. VCC, GND, SDA, and SCL are the four pins of the module. VCC and GND are linked to the power supply and ground of the Arduino, respectively, while SDA and SCL are connected to the Arduino's SDA and SCL pins.

Q5: How do I programme the DS1307 RTC module to set the time?

An Arduino programme may be used to set the time on the DS1307 RTC module. The sketch uses the I2C interface to deliver time and date information to the DS1307. There are several instructions and examples available online that show how to use an Arduino to set the time on the DS1307.

Q6: Can the DS1307 RTC module be used with devices other than Arduino?

Yes, the DS1307 RTC module may be utilised with various I2C-capable microcontrollers. Nevertheless, depending on the microcontroller used, the code necessary to interface with the module may change.

Q7: How accurate is the DS1307 RTC module?

The DS1307 RTC module has a monthly accuracy of +/- 2 minutes. Temperature and other external conditions, however, may impair accuracy.


  • 5V DC supply
  • Programmable Square-Wave output signal
  • Automatic Power-Fail detect and switch circuitry
