Arduino 1-wire Datalogger

Playing with bits of wire.

SD card and RTC tested.

probably will use Lady Ada's fridge logger and SD/RTC test sketches as a template;

combining the RTC and SD examples to test the board have got me pretty close to it already;

https://github.com/adafruit/RTClib


That all works. Need some data.

One wire example picks up the DS1820 easily enough, need to look at humidity.

This looks promising;

Some notes on it here, (may not be relevant)

This looks like Arduino 1 code,  replace #include "WConstants.h" with #include "Arduino.h". That's just something I read here;  http://blog.makezine.com/2011/12/01/arduino-1-0-is-out-heres-what-you-need-to-know/




This does something too...
