Arduino Real Time Clock Relay

For this we will use ds3231 rtc module and relay module.

Arduino real time clock relay.

As mentioned earlier the ds1307 rtc module uses i2c communication. Now that we have seen a little bit about the real time clock ic ds1307 we will proceed with the interface of arduino and real time clock. The ds1302 real time clock on arduino where going demonstrate how to use the ds1302 real time clock with arduino board the ds1302 trickle charge timekeeping chip contains a real time clock and calendar and 31bytes of static ram and its communicating with a microcontroller or microprocessor via a simple serial interface. A real time clock rtc is an electronic time keeping device commonly available as a single integrated circuit.

I ll show you how the tiny rtc is hooked up and how to use two ways including with interrupts. The module comes assembled ready to use with battery supplied. Arduino real time clock and calendar with 2 alarm functions and temperature monitor using ds3231 read ds3231 rtc datasheet to understand the code time date parameters can be set using two push buttons connected to pins 9 b1 10 b2. A real time clock rtc with arduino through the library written by joe robertson.

In this tutorial we will learn how to turn on off anything at a specific time. Sir can you explain a project to play songs at specified times using arduino and to switch on a relay the same specified time so that i want to play songs every hour for a duration of 3 to 6 minutes through a power amplifier which. This post is about how to use the ds1307 real time clock rtc module with the arduino. Today we will add a real time clock to an arduino.

After learning about timekeeping and the ds3231 rtc it is now time to build a project using the ds3231 rtc. You can also follow this guide for other similar modules like the ds3231 rtc. Introducing the real time clock module. Alarm1 and alarm2 can be set using two push buttons connected to 11 b3 10 b2.

Real time clock rtc pcf8563. For this project we will make a simple arduino calendar clock using a ds3231 module a 16 2 i2c lcd and an arduino uno board. The real time clock module is the one in the figure below front and back view. Ds3231 real time clock module.

We ll start by adding a single relay that will turn on for 5 seconds under the condition that it is monday at 2 30pm and will run for 1 second every minute otherwise.
