reccomendations for a 1307 RTC library. there are so many and I don't know which to use
I use this https://github.com/davidhbrown/RealTimeClockDS1307 library and am very happy with it, though I'm not so happy with the accuracy of the DS1307 (mine looses 7.6 seconds per day but have found a clunk way to improve it).
By the time you buy that hardware and get the code to set/reset it it is cheaper to do a GPS... the time signal only needs 1 or 2 sats... works for me...

I even have a problem picking up MSF radio time signal in some places.
I've never done anything with hall effect sensors. I don't understand them. What do they do?
