Hello, I am new to Arduino. I heard that the Arduino Uno is the latest. Lots of books also use the Uno as a board in their examples. I guess this is the one to go. However, I may need several shields. Somebody suggested the Mega. is Mega 2560 probably what he suggested?
1. Is the Mega 2560 (or whatever other Mega you recommend) fully compatible with the Uno? If I follow some books and use the examples, shields described in those books, will I get the same results without any modifications of the software and hardware?
2. What is the maximum number of shields one could add on top of Uno and Mega? How to determine that?
3. Somebody mentioned that if I use a high current motor shield, the number of shields I could add will be reduced. Is this true? That is why that person suggested choosing the Mega.
