ok, keep in mind we are new to arduino and all this.. so we don't understand as much as you guys..
does each pin require a resistor? if so, which?
i thought this thing was going to be fun, so i bought the arduino for my son and a bunch of misc parts on ebay.. so we don't have everything we need, but slowly getting it and getting the parts we need.
so please be patient... i don't want every post i make to turn into an argument with people on here...
if there is a schematic for the exact one we have, we would like to see it... we never wired up a digit led before. we just don't get it atm
