Hi all,
I saw that it is possible to measure votage with arduino analog pins.I understood most of the hardware but I still dont understand how to calculate the appropriate resistors.here is the article i saw http://www.clarenceho.net:8123/blog/articles/2009/05/17/arduino-test-voltmeter. 
I want to thank you in advance for your time. :)

See http://en.wikipedia.org/wiki/Voltage_divider

It's a pretty simple concept and definitely worth your time to learn it fully.
