Deus_Ex_Machina:
Why do you think the pin being a analog one is a problem?
The way I understand it, all Arduino pins can be used as digital in/outputs and some can additionnally be used as analogue ones.
That is entirely true. However what I was calling out is a reason yours might not be working as that is a fundamentally different temperature sensor which also needs the resistor to setup the one wire bus.
If you connect it and try to talk to it with the same code it will not work. It's not an Arduino issue.
Apologies for the confusion, Geoff
