Okay so I've done some reading and am growing ever more enthusiastic about this project. I have a million questions but I'll stick to just a couple for now:
Starting from the very beginning - What Arduino board would I be best using for this?
Regarding the nuElectronics Datalog + I/O shield - which I think would serve me well after reading up on the use of DS18B20s with it- is it possible to both read AND write off of the SD card with this shield?
Or do you feel there is a better fit for my needs than that shield?
Thanks!
