Are things beginning to feel hot in here? Shall we check?

Today we started by working out an overall plan of what we needed to do to get the thermometer working we need to:
1) connect the thermometer to the arduino
2) connect the arduino to the raspberry pi
3) connect the raspberry pi to the internet
Of course, there is a lot more to it than 3 lines but we have made huge progress today.
Firstly, we have succesfully connected the arduino to the raspberry pi by following the instructions on this link http://baldwisdom.com/simplified-setup-for-arduino-on-raspberry-pi/ . Then we succesfully connected the thermometer to the arduino using a simpilfied version of the circuit on the following link http://openenergymonitor.org/emon/buildingblocks/rtd-temperature-sensing / . Finally, we used the code on this website to read a sensor (to be linked later) giving us a resistance. Also, in previous days, as mentioned, we started towards the goal of making the raspberry pi a web server which suggests we are close to completion.
The final steps to be completed over the coming days include:
1) calibrate the sensor so we can get a temperature
2) finish the connection between raspberry pi and internet.
