hello guys ,
iam now currently building a aurdino project for automating my aquarium very simple stuff like
auto topoff
turning on light with relay
automated water change
i have really no idea about engineering and codes cause im a a doctor
i managed to scavenge codes from other projects and managed to build very basic code for the system and for now i managed to make the auto top off and light relay to work and also an rtc to work was a big headache … 
now i am having problem with the auto top off code, i want the system to turn on at 12 everyday run for 3min. then shutdown itried using delay but it is causing the other systems to halt so can u guys guide me how to make it work
and also i want the auto top off pump to run for an extra 3 sec before it shuts down , heard about using mills. but really i dont know how to use it , dont want to use delay cause it is delaying everything , please help me out with this guys
thanks in advance!
