Arduino Temp Monitor : Webserver

Phase 2: Temperature monitoring logged on webserver.

/*
  Web Server
 
 A simple web server that shows the temperature using an Arduino Wiznet Ethernet shield.
 
Parts list:

10k Thermistor
Breadboard/Veroboard
10k resistor
Arduino ( I use UNO)
Arduino Wiznet Ethernet shield

The Thermistor Circuit:
AREF---+3.3V----Therm----A0(Arduino)----10k res---&gt; Gnd

Better Readings:
