Open questions for anyone familiar with Arduinos

Posted on by

And, I’ve got several.  I’m not entirely sure what I’d end up using an Arduino for – perhaps making tiny silly robots.  However, there are so many choices and not a really good way to differentiate among them.

  1. Chips
    1. There appear to be several.  From my friend Google, I understand that the “ATmega328” is significantly better than a “ATmega168” in terms of double the flash memory, RAM, and baud rate.  But, I also see “ATmega328P.”  What’s the “P”?  Is it important?  Does it mean pre-programmed?
  2. Power
    1. I’d like to be able to run whatever Arduino variant I end up with from a variety of power sources.  It’s my understanding that a preassembled Ardunio has that capability – accepting between 5V that could be supplied from USB to 9V from a typical 9V battery to a 9-11V AC power adapter.  If I build a MintDuino, will it only run from a 9V?  Would it run from USB if I use an FTDI cable or an FTDI Friend?
    2. Wait, I may have answered my own question – I’m guessing that a Breadboard Voltage Regulator Kit would be needed to run a MintDuino from a variety of power sources.  Is this the case?
  3. USB
    1. I have an FTDI cable from my Cupcake CNC, so I think I could use that with any kind of board that doesn’t have a USB port.  Having fiddled with an FTDI cable a bit now, I don’t have any preference whether my board has a USB or FTDI interface.  Is there any reason I should?
  4. Programming
    1. Are all of the *Dunio variants identical to program?  I seem to recall reading that the NetDuino is “.NET”  I’m not sure what that means, but I’d prefer to use something that utilizes the Processing environment – if for no reason other than I could use what very very very little processing I was exposed to when fiddling with my Cupcake’s temperature tables a million years ago.
  5. What should I start with?  Please assume I know nothing about electronics, Arduinos, electricity, computers, programming, or things that rhyme with “minternet.”
    1. It’s hard for me not to like the MintDuino package.  A small breadboard, a little tin, some parts, no soldering.  The Mintronics Survival Pack seems interesting too – again a little tin. 12  Is the “Survival Pack” useful?  Useless?  Kinda useful?  It looks like it has a small breadboard, some LED’s, wires, 9V battery clip and wires, etc.  As I understand Arduinos3 , they can accept a variety of voltages.  Will a MintDuino do the same?  It looks like I’ll need an FTDI cable, which I have from my Cupcake, so I’m not overly concerned about this limitation.
    2. Should I go with a fully assembled Ardunio like the Uno, a breadbord kit, or a kit that I solder together?  I’m leaning towards a breadboard to start for simplicity’s sake.
    3. Should I go with a Sanguino, Ardweeny, Arduino Mini, Arduino Pro Mini, Ardunio Mega 2560, TinyDuino SB, Sippino 328, FreeDuino, DC Boarduino, NetDuino, NetDuino Plus, NetDuino Mini, Ardunio Nano, or RBBB?  If so, why?!  Can you understand my choice paralysis here?
  1. I like tins. [↩]
  2. Then again, I’ve got a robot that can make me plastic tins, so they’ve become less fascinating to me. [↩]
  3. Which isn’t much [↩]
