I'm trying to add sounds to my pet enclosure controller. They are tropical so I've snatched 24 hours worth of tropical rainforest sounds and am trying to play them in hour order. Now, I had it sort of working last night except there was no time correlation, just a Player.next() call whenever the player was idle. The issue is somewhere in the playSounds() module just above setup. The if statement is the problem, I think, because the conditions are met going into it, as per the lcd1.print statements, but it will not run the if statements in the {} mostly just a switch case and a soundNow() to buzz a buzzer to let me know it reached there. It's probably something stupid, it usually is with my code, but maybe it just needs a different head to spot it. Any help appreciated?
And now for the code ;

I know, it's a little overkill but I had nothing better to do in my retirement. I'll have to tidy it sometime!
I had the devil of a time trying to hold temp and humidity between allowable levels until I realised I didn't have to. I just picked a median value and forwent the complications. What do you think of it, as a piece of code? Thanks.
