Arduino Relay Trigger at specific time | DS3231 RTC Module 

sooper (am frem india ) am wery happy to waching this video thanks (gog + you) sir

Thanks for the great video

thanks for this video.......

Great 👍👍

Very Cool ! Like !

The video and explanation is great...but the code should be little more vast in considering the fact that if power goes out in between the specified time and the time to be on has gone past then the relay wont be on unless it is the on time in the next day....still working on that part

Thank you for this video. Why not sync arduino board time with rtc and set alarm with alarmrepeat ?

from where can I get the library for RTC DS3231 which works with SDA and SCL pin projects. It's not in examples of Arduino. Please suggest ASAP

Is there a minimum duration I.e can I set the relay to close for 30 seconds?

cool, very good. it has like with just one button whenever it is pressed it resets the count ... and for another project of a soldering iron with vibration sensor I turn it off in 30 minutes if it is not used .. asables I forget and my lining stays on overnight. ..suggest a video with attny85 and a relay or mosfet triggered for 30 minutes-- ok thanks

Sir which gear motor i used for making power full truck

thanks for sharing bro. god bless you. i have one question/ could you tell me bro,,. in 24 hour how to programed double opening the relay in 24 hr and sunday up to sunday

I don't know anything about arduino but i tried to add this code and it works. try this if you want to add seconds and multiple time trigger. #include int Relay = 4; DS3231 rtc(SDA, SCL); Time t; const int OnHour = 1; const int OnMin = 14; const int OnSec = 20; const int OffHour = 1; const int OffMin = 14; const int OffSec = 50; const int OnHour1 = 1; const int OnMin1 = 16; const int OnSec1 = 20; const int OffHour1 = 1; const int OffMin1 = 16; const int OffSec1 = 50; void setup() { Serial.begin(115200); rtc.begin(); pinMode(Relay, OUTPUT); digitalWrite(Relay, LOW); } void loop() { t = rtc.getTime(); Serial.print(t.hour); Serial.print(" hour(s), "); Serial.print(t.min); Serial.print(" minute(s)"); Serial.print(t.sec); Serial.print(" second(s)"); Serial.println(" "); delay (1000); if(t.hour == OnHour && t.min == OnMin && t.sec == OnSec){ digitalWrite(Relay,HIGH); Serial.println("LIGHT ON"); } else if(t.hour == OffHour && t.min == OffMin && t.sec == OffSec){ digitalWrite(Relay,LOW); Serial.println("LIGHT OFF"); } if(t.hour == OnHour1 && t.min == OnMin1 && t.sec == OnSec1){ digitalWrite(Relay,HIGH); Serial.println("LIGHT ON"); } else if(t.hour == OffHour1 && t.min == OffMin1 && t.sec == OffSec1){ digitalWrite(Relay,LOW); Serial.println("LIGHT OFF"); } }

Greatly appreciate the tutorial, if I wanted the relay to be triggered in seconds would I add “const ins onSec =“ & “const ins offSec =“? Thank you!!

May I have a circuit and code for automatic water pump to extinguish the flame using relay,flame sensor and esp32.

What is the website you used for designing your circuit?

Which software you will use to design circuit diagram

Hi. I'm very new to this. will you be able to share the same setup but with 4 channel relay module. Because in my greenhouse I have 4 water lines. My AC water motor is not powerful enough to pressure all 4 lines at the same time. my plan is to open one line with motor in 15min intervals. Will you be able to help me with the coding.

How set defferent times of activation in a day?

Nice clear video. What software package do you use to draw the circuit diagrams?

I want to display connect with this circuit then how will be connected please reply..

Have already built the thing to keep the school at time

I know I'm like crazy late to the party here, but I was wondering which library you're using for the DS3231 as the one I'm using isn't compatible with your code. Thx!

I have a project... A board with 10 leds each representing the subjects on a time table for a class... How can this project be modified to light up just one led at a time when the time for the subject is due and to switch it off after the lesson period is over and then switch on the next LED until it circles through the ten subjects(LEDS)... I will really appreciate if I'm being replied?

Hi sir Can you send code for digital clock with P10 LED module

nice job, unfortunally I cannot find the example code for DS3231 in my arduino example program :(

can i get the latest link for this code timer?i cant open that link at discription,..

where can i download the library ds3231.h ?

can you put here my friend the library for ds3231 rtc module

In the circuit diagram it shows two jumper wires connecting to the 5V on the arduino UNO ? you can only fit one of the jumper wires in there Does one of them connect to the 3.3V?

How to use for multiple relays 6 ?

How can I download the DS3231Serial_Easy library.I tried so many times but I couldnt find it.pls help me. thanks.

Good video! Three questions: 1. Is there a separate code for the DS3231 board? 2. How do you add the DS3231 library? What is the EXACTE library name? I cannot find the "DS3231_Serial_Easy" library. 3. I'm building a circuit relay switch for a school bell system. How do I add multiple times? I only want the relay to be triggered for 3-5 seconds.

how can i adjust the code so that i can triger the relay two times in a day.

it's easier than I thought. The code link doesn't work. can you put it again in the comments? than you a lot

I try your code does not work DS3231 rtc(SDA, SCL); exit status 1 'DS3231' does not name a type; did you mean 'CS21'? This message comes to me

If it for 3 time a day and last for 5 minute and exactly same time next day and so on.
