Arduino Real Time Clock Relay

In this tutorial we will learn how to turn on off anything at a specific time.

Arduino real time clock relay.

Alarm1 and alarm2 can be set using two push buttons connected to 11 b3 10 b2. The real time clock module is the one in the figure below front and back view. This post is about how to use the ds1307 real time clock rtc module with the arduino. 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.

I ll show you how the tiny rtc is hooked up and how to use two ways including with interrupts. Ds3231 real time clock module. Real time clock rtc pcf8563. For this we will use ds3231 rtc module and relay module.

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. Today we will add a real time clock to an arduino. 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 is an electronic time keeping device commonly available as a single integrated circuit.

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. The arduino card measures the elapsed time since the module was turned on in ms. In the arduino real time clock i2c interface the arduino microcontroller always acts as master and the ds1307 acts as slave. As mentioned earlier the ds1307 rtc module uses i2c communication.

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. A real time clock rtc with arduino through the library written by joe robertson. Introducing the real time clock module. The module comes assembled ready to use with battery supplied.
