Hi,
My project is about measuring some data, send it to xively and object detection.
My project will contain:
3 proximetry sensors (Digital connected preferred)
1 wifi module for xively.com
3 LED
1 lcd display
Which arduino board would you recomend for my project? I'm new in the electronic part, but good in coding.
I always recommend the Uno R3 with DIP mega328 as a starter board. There are more tutorials, examples, shields and just about everything for the Uno than any other Arduino. And the chip is replaceable for when you accidentally toast it.
I have had an eye on the uno R3 board too, but need another opinion. so thank you, i go for the uno R3 :.
You are likely to to want to do more than you think, and will then need a Mega. So you might as well get it now. It doesn't cost much more, is just as easy to use, and when the time does come when you need one, it is guaranteed to make life easier than trying to squeeze your programme into a Uno.

That is not a requirement I can understand. Are you trying to some HTTP GET POST stuff or is it TCP/UDP? Most arduino compatible modules can do all that but you should be more specific what you need. This feature will cost you something around $50-$80 USD. I have been using the expensive Arduino official wifi shield and have started migrating to the less expensive xbee wifi module + wireless shield.
