Using Millis to Turn On/Off Relay for a set interval

Hi gcjr-

I agree the formatting is bad in my post after seeing yours. It makes review difficult. I will be reformatting in the next revision.

This is true which is why I was thinking about using while conditions for the the pressure ranges that the compressor would be on and off. I think that would solve the issue of the currentMillis being taken over and over. Is this a logical solution to you?
