Uno R3 is your best bet. Simple to use and is the basis for most projects. Plus, it has USB for communication while some other boards don't.
What about the "RedBoard" ( https://www.sparkfun.com/products/11575 )?
Earlier quoted context omitted.
For that purpose, the redboard is essentially the same as an UNO. I have one of each and can swap them out with no problems.
Redboard also has a USB mini connector, not the full sized square one that standard Uno has. Personally I'd prefer the mini connector, I've always thought that the USB connector was the most oversized thing on an Arduino board.
$3 for a micro controller as powerful as the Pro is absolutely insane. I remember paying 10x that price for some components for an early generation Arduino back in college 5 years ago. Eventually I'm sure that $3 will be the normal retail price for these boards, at which point I think we will start to see some amazingly disruptive disposable electronics emerge. Isn't it great to live in the future?
The arduino is really just a breakout board for a microcontroller made by Atmel, with a simplified development environment to lower the barrier to entry. The microcontroller chip itself has always been a couple of dollars, and was before the arduino was invented. Really you could say that paying $20/board to break out a $2 chip was the insane bit (of course, if it makes the difference between you tinkering and not ti…
The LPC810 is neat, but very limited in flash memory and I/O. Check out the NXP LPC1114FN28--it's a 28 pin breadboard friendly DIP package ARM cortex M0: http://www.nxp.com/products/microcontrollers/cortex_m0_m0/lp... 32k of flash and a similar amount of I/O as the ATmega328P used in an Arduino. The big advantage of ARM is that you can use free in circuit debugging tools like OpenOCD to debug and step through code in real time on the chip. It's not easy to do that on an Arduino without a $50+ adapter.

I like & use the LPC Expresso stuff too, but you can do a lot with an Arduino.
