Ez alapján mennie kell:

[code]
#include <DS3231.h>

int Relay0 = 4;
int Relay1 = 5;
int Relay2 = 6;
int Relay3 = 13;

DS3231 rtc(SDA, SCL);

const int OnHour0 = 12;
const int OnMin0 = 24;
const int OffHour0 = 12;
const int OffMin0 = 25;
const int OnHour1 = 12;
const int OnMin1 = 26;
const int OffHour1 = 12;
const int OffMin1 = 27;

void setup() {
Serial.begin(115200);
rtc.begin();
pinMode(Relay0, OUTPUT);
digitalWrite(Relay0, LOW);
pinMode(Relay1, OUTPUT);
digitalWrite(Relay1, LOW);
pinMode(Relay2, OUTPUT);
digitalWrite(Relay2, LOW);
pinMode(Relay3, OUTPUT);
digitalWrite(Relay3, LOW);
}

void loop() {
t = rtc.getTime();
Serial.print(t.hour);
Serial.print(" hour(s), ");
Serial.print(t.min);
Serial.print(" minute(s)");
Serial.println(" ");
delay (1000);

if(t.hour == OnHour0 && t.min == OnMin0){
digitalWrite(Relay0,HIGH);
Serial.println("LIGHT ON");
}

else if(t.hour == OffHour0 && t.min == OffMin0){
digitalWrite(Relay0,LOW);
Serial.println("LIGHT OFF");
}
if(t.hour == OnHour1 && t.min == OnMin1){
digitalWrite(Relay1,HIGH);
Serial.println("LIGHT ON");
}

else if(t.hour == OffHour1 && t.min == OffMin1){

Serial.println("LIGHT OFF");
}
}
