    Cool project.  Which parts do you have working so far?  I would think that the LM75 data sheet should be of great help to you.  Also you need to search at arduino.cc. 

    I could not locate any LM75 info at tronixstuff.wordpress.com.  It is a great place to get up to speed with arduino uno.

     

    REF: lm75a.pdf

    "I2C-bus serial interface

    The LM75A can be connected to a compatible 2-wire serial interface I2C-bus as a slave

    device under the control of a controller or master device, using two device terminals, SCL

    and SDA. The controller must provide the SCL clock signal and write/read data to/from the

    device through the SDA terminal. Notice that if the I2C-bus common pull-up resistors have

    not been installed as required for I2C-bus, then an external pull-up resistor, about 10 kW,

    is needed for each of these two terminals. The bus communication protocols are

    described in Section 7.10."
