Hey everyone, new to the forum, thanks for all of the great information here... Anyway I'm looking at putting together this LED light suit with a buddy, at the same time we'll be getting into Arduino for the first time pretty much: http://shanesalta.com/projects/iphone-controlled-light-up-led-suit/ Before even getting started we have a few questions, like; - How exactly are so many LEDs individually controlled from an Arduino Pro Mini? - What is the purpose of the voltage regulator in this project (where does it go)? - Lantronix seems to have several 802.11 b/g MatchPort wireless "modules" but do we want the "Device Server" or the "AR Embedded Device Server"? http://gridconnect.com/nsearch/?keywords=matchport+lantronix - We noticed in the Arduino sketch application there are two 3.3V Arduino Pro Mini devices listed, is it possible we need one of these and not the other? Thanks in advance for any help, obviously we're very new and just getting our hands dirty.
