Hi,

I am new to arduino and I am thinking of purchasing the uno. However I wanted to know is there any specific reason to get the uno over the mega? I know the mega has more connections and in the long run would/might be better. However as a beginner is this advisable.

I know how to program (rather then just know one language). I am a compentent linux/network engineer by day so Im hoping this wont be too much of a learning curve.

I wanted to get the Arduino just to play with some simple projects etc..

Then I would go for the Uno. You can always add extra ports to that if a project needs it. Also with the socketed chip (if you can get one) they are a bit easier to repair if you blow it up.

Not so quick, it took me four minutes to reply.  :)

Also consider shield usage. Some shields are not compatible with the Mega because they depend upon special-function pins that are in a different place. For example, the SPI and I2C/TWI pins are in a different place on the Mega than on the Uno. It is possible to work around it through breakout shields, cross wiring, etc. but it is a consideration.

how about this kit?

one of the things I want to do is create a mini robot which you can send instructions to and it follows the path. For example like a old mouse program


move forward 10
turn left 120 angle

and it draws  a pattern on a piece paper

Hi,
Take a look at Babuino: http://babuinoproject.blogspot.com/ Which is a Logo project with Arduino.

You can buy an Arduino "Open source copy" AKA clone for about $20 here: http://arduino-direct.com/sunshop/index.php?l=product_list&c=1 and there are other variants too.


DISCLAIMER: I mentioned stuff from my own Shop...
