Hi to all
I am trying to make an arduino on a breadboard based on the excelent tutorial of ITP (http://itp.nyu.edu/physcomp/Tutorials/ArduinoBreadboard)

concerning the Pin 20 - AVcc it says ''Suppply voltage for the ADC converter. Needs to be connected to power if ADC isn't being used and to power via a low-pass filter if it is (a low pass filter is a circuit that cleans out noise from the power source, we aren't using one) ''

I am confused and need your help..Do I need to use it if I am to use ADC? where do I find out about that filter(if I need it)? :-/

Connect it to arduinos 5v pin.

where do I find out about that filter(if I need it)?

The Modern Device Bare Bones Board (http://www.moderndevice.com/products/bbb-bub-cable-package) does incorporate that filter. Take a look at the documentation or buy one of their boards.
