I want to use relay with real time clock module ds3231 to make a self watering machine with the combination of water pump,thats why i need relay,i set up the watering time on 7 am to on the relay and setr the water pump to push out water and i also set the relay to off back after 36 seconds,then it will water the plants again at 5 pm.but when i upload the code,the relay always on and didnt follow as i set up in the code,the relay also didnt turned on when the time is 7 am and 5 pm.Anyone who knows about this please help me to fix it,i really need to fix it quickly. This is the code:

#include <DS3231.h>
DS3231 rtc(SDA, SCL);
#include <Servo.h>
Servo servo1;
char time;
char d;
int Sec;
int Min;
int Hour;
String Day;

void setup() {
Serial.begin(9600);
pinMode(40, OUTPUT);
pinMode(41, OUTPUT);
servo1.attach(7);

rtc.begin();
rtc.setDOW(WEDNESDAY);
rtc.setTime(13, 59, 45);
rtc.setDate(1, 1, 2014);

time = rtc.getTimeStr();
d = rtc.getDOWStr();

}

void loop() {
{Serial.print("date:");
Serial.print(rtc.getDateStr());
Serial.print(" -- ");
Serial.print("time:");
Serial.println(rtc.getTimeStr());
Serial.print("..");
delay(1000);}

if (Hour == 14 && Min == 0 && (Sec == 0 || Sec == 36)){
servo1.write(45);
delay(2000);
{pinMode(40, HIGH);
pinMode(41, LOW);
delay(8000);}
{pinMode(40, LOW);
pinMode(40, LOW);
delay(2000);}
servo1.write(75);
delay(2000);
{pinMode(40, HIGH);
pinMode(41, LOW);
delay(8000);}
{pinMode(40, LOW);
pinMode(40, LOW);
delay(2000);}
servo1.write(115);
delay(2000);
{pinMode(40, HIGH);
pinMode(41, LOW);
delay(8000);}
{pinMode(40, LOW);
pinMode(40, LOW);
delay(2000);
}
}
else if (Hour == 14 && (Min == 0 && Sec == 37)||(Min == 0 && Sec == 59)) {
servo1.write(0);
pinMode(40, LOW);
pinMode(41, LOW);
}

else if (Hour == 14 && Min == 01 && (Sec == 0)||(Sec == 36)){
servo1.write(45);
delay(2000);
{pinMode(40, HIGH);
pinMode(41, LOW);
delay(8000);}
{pinMode(40, LOW);
pinMode(40, LOW);
delay(2000);}
servo1.write(75);
delay(2000);
{pinMode(40, HIGH);
pinMode(41, LOW);
delay(8000);}
{pinMode(40, LOW);
pinMode(40, LOW);
delay(2000);}
servo1.write(115);
delay(2000);
{pinMode(40, HIGH);
pinMode(41, LOW);
delay(8000);}
{pinMode(40, LOW);
pinMode(40, LOW);
delay(2000);}
delay(10000);}
else if (Hour == 14 && (Min == 1 && Sec == 37)||(Min == 2 && Sec == 0)){
servo1.write(0);
pinMode(40, LOW);
pinMode(41, LOW);

}

}

Are you perhaps using pinMode() when you mean digitalWrite() ?

3

yeah,pinMode and digitalWrite are same command right?

4

Yes, of course they're not.
They're not even spelled the same.

Please remember to use code tags when posting code.

5

so,you guys have any recomendation for me to fix this problem?

6

Yes, use pinMode when it is appropriate to use pinMode, and use digitalWrite when it is appropriate to use digitalWrite.

And use code tags.
