The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started

BAD: The soldering workmanship is very disappointing; the worst I've ever seen in a production job. SMT devices on the top seem to be mounted OK, but the bottom of the board had numerous defects in the (wave?) soldering. Two of these joints appear to have been manually touched up (residual flux present). Several other joints had large gaps in cold solder joints, but were apparently not bad enough to warrant manual repair. I hope the Italian manufacturer (SMART PROJECTS) works out these process kinks soon.
*** UPDATE July 2012 *** My subsequent purchase of an UNO-R3 board indicates that the soldering issues in early production boards have been solved. (FYI, CanaKit is an approved distributor for Arduino.)
The Arduino concept is terrific, and has enabled a LOT of people to easily create smart projects. The C compiler and IDE work well; I've never had an easier time writing an embedded application, and the price can't be beat. The only thing lacking is the ability to debug code via single-step.
And on top of that, it wouldn't work when I plugged it in.
Be careful! You're better off buying through a site like Sparkfun or Adafruit.
Seems very well constructed and genuine to me.
I used a spare USB cable and hooked it to a laptop with WindowsXP. Downloaded the software from [...] followed the instructions for WindowsXP and within minutes the 'Blink' sketch was up and running. Had same (smooth) experience on the iMac, in fact with less number of steps (no driver installtion step).
With few LEDs, an 8 Ohm mini-speaker, few resistors and under half an hour I had couple of 'sketches' tried and tested already. My kids are now super-interested in electronics after enjoying the sweeping LEDs and interesting tones and of course the appealing Ardunio R3 board! I let my daughter change the delay intervals in a 'sketch' and she was so glad to see the effect right away.
Bottom line: After running some sample sketches and my own programs - the board seems to be functioning well.
Regarding the Arduino concepts:
1. I absolutely love the simplicity of the development environment (IDE). You can truly jump into the interfacing and control aspects of a microcontroller device without getting bogged down by its internals, assembly instructions and potentially complex program download steps.
2. This is a great learning tool to introduce yourself to the embedded software and the base hardware.
Arduino R3 is probably one of the cheapest development boards out there yet very effective.
Only other board I have had a chance to play with is the Atmel AVR Butterfly (which costs around $20) but the overall development setup is definitely more complex.
So in case you have even a 'tiny bit' (no pun intended) of interest in the vast world of microcontrollers and electronics in general - go ahead and try this board.
Note: Related purchase (from Amazon) which helped me a lot is - the book 'Programming Arduino' by Simon Monk.
