Im a student who new to arduino. I learning about arduino actually and im interested in it. I wanted to know whether arduino duemilanove can be used for 5V adc? What is the difference of arduino uno and arduino duemilanove. Ur help is really appreciated, thanks..

It's adc is 5volt  and the only difference is how they connect to the pc the uno  uses a atmega16u2 for USB to serial and duemilanove uses a FT232RL and only has 5 volt power uno has 3.3 at 50ma and 5 volt

duemilanove also provides 3.3vdc at 50ma to the shield power connector, it comes from the FTDI chip.

From a writing sketches and wiring up to external components the duemilanove and Uno are 99.999% identical. Only difference is UNO has a slightly smaller bootloader so duemilanove has slightly smaller flash size and uploading sketches is twice as fast on the UNO. Eith board is a great way to get started learning about arduino programming.

"Only difference is UNO has a slightly smaller bootloader"
and duemilanove can be reprogrammed with that same bootloader once you learn some more - but in your initial programming it will not be a factor.
