Arduino Relay Trigger at specific time | DS3231 RTC Module

[@shiroeschulz4515]

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"); } }

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

[@navigator4077]

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

[@vishnujayakumar1229]

How set defferent times of activation in a day?

[@Infinity2u]

What is the website you used for designing your circuit?

[@zacmrochko436]

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.

[@jonitube4667]

how did your project go? I am trying the same project now and I would appreciate it if you would help me out. [e-mail]

[@johnmarksiatriz3725]

Every day in will trigger the power on if you set a example 22:40 and it will power off 22:41?

[@pretendanought]

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

[@firaolmekete4201]

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
