hi. what i want to create is a small multifunctional device that uses a 20x4 LCD display. its main function is to be a song selector for my band. with the push of an onboard button, it randomly chooses one of the values (songs) that i have entered in the code sketch.
my question is... what arduino board is good for that? i've seen a tutorial online for the Duemilanove board. however, the Ardweeny sold on makershed.com is the smallest (and cheapest) board. could i use that? what are the differences?
also, what is the maximum number of variables arduino can handle in a randomized routine as the one described above?
and finally, i want the device to display the time/date when not in use.
but right now, i need help determining what exactly i need to purchase in order to get it together. Ardweeny? Duemilanove? Something completely different? Does it matter?
thanks in advance
