So, i saw the LED cube experiment and decided that i would try one myself. Although i can definitely say i am a newbie when it comes to microcontrollers, i still would like to try and understand them. I am planning on making a 4*4*4 or 5*5*5 cube, and dump the programs that the various users have submitted. Now, most of the instructables have not specified which arduino board they used, few have, and those who did, each his own. My questions are:
What are the differences between them?
I mean, i saw a Due, Fio, Leonardo, Uno, Duemilanove etc etc.
Are they interchangeable?
Secondly, which one is better to use for the cube project? Or all the one and the same? Personally, in my area, Duemilanove is pretty cheap.
Third, i would really love to understand the basics of arduino, and also learn to program it. So, if anyone have any good site or tutorial or other resources for a COMPLETE newbie like me, please do point out!
