I am sorry but I can make no sense of the title of this thread.

What problem are you trying to solve ?

i want to power ON my 1 hp water pump for 30 seconds and then power it OFF after the 30 seconds is up, and start the pump ON again after 2 hours..Please help. My friend wrote the codes for me. He wrote the code so that the pump will be ON for 5 minutes.

Have you any idea on how the code works?. Could you describe it in two paragraphs?

Regards.

the codes are for powering a 1 hp submersible water pump ON and OFF using an arduino uno, a 4 channel relay and a ds1307 rtc.

i want to fill my water reserve tank at home from the water well. but i have very limited amount of water being collected at the well. so as to maximize the collection time i want use the arduino to help me switch the pumps on and off after every 2 hours for 30 seconds which probably gives me 60 liters of water.

i have no idea about programming. my friend wrote the code for me but he made the relay switch ON for about 5 minutes. Running the water pump ON for 5 minutes will burn the coils in the pump without any water in the well. so i want to decrease the pump running time from 5 minutes to 30 seconds. Please Help and thanks in advance

Since it’s the only thing in the first post, I figured it was worth posting PROPERLY in </> code tags !

You might try changing

if(min>1 && min<6)

to

if(sec>1 && sec<30)

It's about 10 lines down from
void loop()

Hi,
Frankly, I do not see the point on (trying to) helping somebody that does not understand nothing of the code.
Regards

Thanks a lot. Will change from mins to secs.
