Digital Temperature with the Arduino

Arduino One Wire Temp SensorI was waiting on an order I had placed with Tayda Electronics (they rock) for my One-Wire temperature sensors.

If you haven't heard of One-Wire or these particular sensors you need to check them out. They are made by Dallas Semiconductors and they are amazing. They are a bit $$, which is why I opted to have them shiped from the philipeans directly. I got them for $1.60/each as opposed to ~$5.00/each from any of the domestic online retailers. The shipping only took ~8 days and the shipping was only ~$4.00. Can't beat that huh?

Anyhow, I got them in and wanted to see them in action, so I threw together a quick circuit which reads the temp and displays it on a LCD screen I had laying around (got it here). The end result is a quite nice and very accurate thermometer! I've posted my code and some high-res pics in the attached ZIP file below if you are intrested. Get your LCD working as outlined in the adafruit document and then hook up the one-wire sensor.
