Step 1 of 98 was completed tonight. I successfully communicated with 3 1-wire DS18B20 temperature sensors thanks to a great tutorial on Hacktronics.com. Also, I think I finally understand the "pull-up resistor" concept, and with the Ohms law I learned earlier this week, I might even be able to calculate the current flowing (V/R = I ) to the 1-wire bus.
I can't wait for the Ethernet shield to get here so I can start working on the next phase of the Arduino project...connecting the house sensors to the Interwebs.
