Now the logistic growth function is working.  This is very nearly complete.  Now I just need to add the music functionality for the alarm. Also, the non-volatile ram that's usually associated with DS1307 chips does not appear to be working at all.  That could be because I'm using a DS3231 chip instead and the breakout board may not have the same memory chip.
