What do you mean by "proto board"?http://en.wikipedia.org/wiki/Breadboard
By proto I mean the unit that is sitting on my desk that would be used to develop, modify and test "sketches" on. Not the final product, but the prototype. I would prefer the prototype while in development stages to not require soldering when possible as I am not an all knowing master of engineering and am prone to mistakes. With all due respect this
is why in my other thread I specifically asked if there was a place for beginners.
Is there anywhere that the Sanguino board excels on where the other is lacking? So the Mega 2560 is the best board that can be bought at the moment? Do all boards do the same thing? There is no difference between the Uno vs. Lilly?? There are certainly variations this is why I am asking a forum of people that might know these variations and how they would correlate to a beginner.
If you need more I/O pins than Sanguino, your selection is already done.
I don't know that I need anything, this is why I am asking the questions. I don't know everything I would like to try however if I buy a Nano board and discover 2 months later all I can do is make some lights blink and a couple beeps then I would clearly be disappointed if I find that another board would have suited my interests better. All I am asking is what Arduino (or Arduino compatible) board would be considered the most powerful and lending the most features, thus offering the most options for development on. I tried to make it a black and white question, again sorry for the confusion. To make it as clear as I can, what is the best Arduino board?
Thank you for your time and efforts KE7GKP, I appreciate your help.
