Thoughts of an Electronics teacher new to Arduino: I'm thinking about buying just the Uno R3, as I have all the basics (breadboards, pots, etc.) but I note there are a couple of possible items I might want to purchase, specifically, "Getting Started with Arduino (by Banzi), the Data Logging Shield, and the Proto shield. OF course more is better, BUT more expensive. Should I buy more than just the R3? If so, what?
