[OpenTRV-dev] DS18B20 with Arduino

[Kevin Wood]

It seems that the code I used was derived from this:

http://www.siwawi.arubi.uni-kl.de/avr_projects/tempsensor/

There's no mention in the code or the web site of any license or
permission under which it may be used, unfortunately. At the time, that
didn't bother me, of course...

It's not that complex, and I have onewire devices, so I could attempt to
"white room" myself and write something?
