Hi Justin,
Thanks for your interest! As a complete beginner, realistically an Arduino Uno or Due is probably a better bet, just because there easier to play around with things and get a feel for electronics and the Arduino platform. That being said, it's not that hard to jump straight to a TinyDuino, but it is a slight bit more advanced than a standard Arduno. Most people with a little Arduino experience can pick it up in no time, but for someone completely new to it, it may be easier to start with a standard Arduino then transition to a Tiny later.
Thanks!
