ArduinoUno REV3 [A000066] – ATmega328P Microcontroller, 16MHz, 14 Digital I/O Pins, 6 Analog Inputs, 32KB Flash, USB Connectivity, Compatible with Arduino IDE for DIY Projects and Prototyping

Like everything with the Arduino name its nothing but high quality. Don't buy clones use the real stuff and support the people behind this amazing device with no problems usind IDE software

I'm a senior nearly 70 and never touched any Arduino or anything similar. I wanted the device to reset a color printer item with an already written program. I have never written any code and boy am I learning. One simple character mistake and running the compile program will surely tell you. I am using the Arduino IDE 2.1.0 program with this Uno Rev 3. Nevertheless I am happy with this little thing and there are so many projects out there in the community, this will surely keep my mind going and my interest.Setting up was easy. I first got the Arduino IDE program (free on the net) and installed... went fine on my Windows 10 computer with no problems. Once installed, I connected the Uno Rev 3 to my computer via the USB port only (no ext power supply used). Plugged into the USB port, about 3 seconds (literally) later it already installed drivers and the thing was running. It selected Com Port 6 on my Win 10 system. On the Arduino IDE program you just have to make sure you select the Arduino Uno Rev 3 from the list... that is it, and your up and going. From beginning to end I probably spent 5 to 10 minutes doing everything to make it run.On Ease to use and Easy to learn, I gave a 4 star only because I have never done anything like this. If you are a pro or some kind of advanced user, or if I was, I would give a 5 star across the board. This is only my first day trying it, so I will update later on.I checked out Youtube video's and tried writing / typing 3 different programs on the Arduino IDE screen. I ran the compiler program on the IDE... said it was good, tested it in the simple serial monitor (included in the Arduino IDE) and was interesting to watch the board respond. I then saved my program for later.

Board works great! The R4 WiFi does not work with Windows so we were happy to see this model be recognized. The board was sent in a bubble mailer and had damage to the box but the board itself seems to be fine. A small box instead of a bubble mailer would be great. The board is really fun and we already built a range finder!

Regarding the board: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.

high quality everything on it is perfect

GOOD: This is indeed the Rev-3 UNO board with the reset button in the upper left corner. It arrived very quickly and seems to work well so far. My C-language test "sketches" (apps) downloaded and ran on the first attempt, using the version 1.0 software download. The components and PCB appear cosmetically to be of reasonably good quality, but ...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.
