Frequently Asked Questions (FAQ)

  • Q: Where can I find a DS1307 and Arduino hookup guide?

    A: In the Arduino Real Time Clock Tutorial, we will learn about Real Time Clock (RTC) and how Arduino and Real Time Clock IC DS1307 are interfaced as a time keeping device. If you recall, we have already implemented an Arduino Alarm Clock using RTC DS1307 in an earlier project. more

  • Q: How do I make a DS1307 RTC digital clock?

    A: What is DS1307 IC actually? Well, it is a Real Time Clock (RTC) IC that is simple to use, low cost and easy available. The IC basically is able to count the date and time accurately and it will continue its counting if the backup battery – coin cell battery is there although the mainsupply to the IC is cut off. more

  • Q: Where can I find the DS1307 Arduino library?

    A: For the RTC library, we'll be using a fork of JeeLab's excellent RTC library, which is available on GitHub. You can do that by visiting the github repo and manually downloading or, easier, just click this button to download the zip. more

  • Q: Where can I compare the DS1307 to the DS3231?

    A: We keep getting requests on how to use DS1307 and DS3231 real-time clock modules with Arduino from various sources – so this is the first of a two part tutorial on how to use them. For this Arduino tutorial we have two real-time clock modules to use, one based on the Maxim DS1307. more

  • Q: Where can I find the Adafruit DS1307 real time module specifications?

    A: This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC - but it requires 5V power to work (although we've used it with 5V power and 3.3V logic successfully). more

  • Q: Where can I find a DS1307 pinout diagram?

    A: Real time clocks (RTC), as the name recommends are clock modules. The DS1307 real time clock (RTC) IC is an 8 pin device using an I2C interface. The DS1307 is a low-power clock/calendar with 56 bytes of battery backup SRAM more

  • Q: How do I connect a DS1307 with a Raspberry Pi?

    A: After a lot of research I came up building my own RTC using DS1307. I will be using my RTC with Raspberry Pi. I would have purchased a module but that was way too costly..so I decided to build my own. more

  • Q: What is the best DS1307 RTC module on the market?

    A: The SparkFun Real Time Clock Module is a simple breakout board for the DS1307 real-time clock (RTC). It can accurately keep track of seconds, minutes, hours, days, months, and years for almost a decade, so your microcontroller doesn’t have to. It’s the perfect component for clocks, calendars, or any other time-keeping project. more

  • Q: How do I build a real-time clock circuit with a DS1307 Chip?

    A: In this project, we are going to build a real-time clock using a DS1307 real-time-clock chip. We will show how to build a RTC circuit from scratch using the DS1307 chip.A real-time clock, or RTC, is an integrated circuit that keeps track of current time. It can keep track of all time from the year down to the second. So it's a very versatile chip. And it can keep track of time in either 12-hour or 24-hour format. more
