Spa Temp Control

My goal right now is figuring out how I can make the pump turn on at 75 degrees but stay on for say 1 minute regardless of the water temp dropping below 75 which currently turns it off. I like that the water temp is constantly updating and if I add a delay to the else statement it slows down data collection on water temp which isn't how I would like it to work.

You will need to restructure your code using millis() to keep track of time rather than delay(). Also I think you would benefit from using a state machine and it would make it easy to add functionality later on as well.

Look at the following tutorials:
