How to connect the RTC module to the Arduino?
Connect your Real Time Clock module to your Arduino as in the schematics below. Working with the RTC requires two important steps: retaining the time, so that the RTC always gives the correct time, even when it is turned off For setting the current time you need to change the code provided.
Are there different ways to control electronic relays?

What kind of oscillator does an RTC use?
A real-time clock is a clock that keeps track of the current time and that can be used in order to program actions at a certain time. Most RTCs use a crystal oscillator (like in the Arduino Zero) whose frequency is 32.768 kHz (same frequency used in quartz clocks and watches).
What can I do with a zero RTC board?
Zero, MKRZero or MKR1000 Board) to control and use the internal RTC (Real Time Clock). A real-time clock is a clock that keeps track of the current time and that can be used in order to program actions at a certain time.
How to use DS1307 RTC with Arduino Uno?
Connect the SDA and SCL pins of the DS1307 RTC to the SDA and SCL pins of Arduino i.e. pins A4 and A5. A 16×2 LCD is connected in order to display the data and time information. The connections are made as per the circuit diagram. A simple project where Arduino UNO is interfaced with DS1307 Real Time Clock is implemented here.
How does the Arduino module retain the time?
As you can see in the picture above, the module has a backup battery installed. This allows the module to retain the time, even when it’s not being powered up by the Arduino. This way, every time you turn on and off your module, the time doesn’t reset. This module uses I2C communication.
Why do we need a real time clock ( RTC )?
An RTC is battery powered and keeps track of the current time even when there is no power. Real Time Clock ICs are present in computers, servers, many embedded systems and in fact they are used wherever it is required to keep an accurate time.
