Anybody out there got experience with Raspberry Pi and a DS18B20 temperature sensor?

I’ve followed instructions through various sites which have all given the same information about wiring the DS18B20 sensor to a Raspberry Pi (red is 3.3V, black is ground, white connects to GPIO pi…

    I wondered if it was a voltage or resistance problem. A comment on StackExchange said to get a volt/ohm meter, which sadly I haven't owned since college, so I'll pick one up this week. Just unsure whether to order another sensor or try to take this one back or what.
