- Uno 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

This Arduino is a very quality build, From now on I will buy name brand items when possible. This is well worth the extra pennies.

Perfect functioning and pin-for-pin match for a generic unit I burned up and needed to replace in a small learning kit. Plug and play install, basically. These are supposed to be more robust as well, so we'll test that, too... I also love the little included tray the board fits perfectly into as well!

There’s a reason this is one of if not the most popular microprocessor, at least for beginners. So easy to use. Compatible with nearly any other component. Compared to most microprocessors, it’s a great price for what you’re getting. Quality is consistent and long lasting.

Great device. I bought 3 of these and they are my go-to controller for some pretty sophisticated DIY projects. Do read about how not to over-drive the pins (demanding too much current from them). And, DO read about the difference in the +5v and "Vin" pins. There is a company that sells just the processor chip. They are reasonable (pkg 3) and I recommend having them on hand in case Murphy stops by for a visit. If you follow basic principles and NEVER try connecting a pin to something for "trial & error" but instead, be certain of the voltage AND current potential that you are supplying (or demanding), and this beautiful device will work like a horse. When it comes to your connection to the computer, some Windows serial "portage" issues arise but it's a matter of persistence. The Arduino IDE (programmer) has ways to let you see how things are going and which PORTs are connected and working. This is the only part that can be frustrating (other than writing software bugs. :-) Enjoy.. here's what I think about it and how I use it this week: Have fun: Keep in mind that if your project is complex and you need more pins, you can use the nice I2c bus that this UNO has available and you can connect Slave devices to expand the "pin-age". :-) I am going to add a AdaFruit Trinket Pro (powered from this UNO 5v bus) and let these two guys talk to each other over I2c; exchange info, and I get tons more PWMs and digital pins too. The cool thing is that the Trinket fits right on the back of this UNO's added shield. SWEET !! As usual, these are great. Notice that this is the R3 -- exactly what you want. I've written some great control software for controlling the RF oscillator in radio transmitters and this made the project a success. I added a stacking shield (Gikfun Prototype) for the additional hardware I needed and this UNO allows the flexibility of updating my own sketches if a new feature in my RF unit is warranted.

This is a micro-PLC. (Programmable logic controller). The setup () loop does first time execution. the loop() does continual scanning of Inputs and writing outputs. I'm an electrical engineer and control systems engineer, and I was enjoying learning to program the arduino as an embedded controller (PLC). The arduino.org arduino is a spec product (same as other Chinese knockoffs, but as long as they meet spec, they are a hammer...just not with the same namebrand). If you look on the web, arduino.cc is the Italian webpage with rights...but arduino s.r.l. also says that they have rights. it is confusing. the software from arduino.org for the ARDUINO IDE (The programming environment to make arduino code, to compile it, and to push it to the controller) is software revision 1.7.5. When you load it, it says that it is a modified version of the arduino.cc software. this is messed up, as arduino.cc has version 1.6.5. I found it suspect after installing the .org software so I uninstalled, ran a virus scan, and installed the .cc software. (.cc software will work on any arduino that meets the arduino specification). All in all it is a cool product. for intro to programming, it gives quick results. if you are a control systems engineer like me, then you have a $25-ish PLC that you can make to do any amount of awesomeness (provided that you use the 14 digital In/outs and 6 analogs to accomplish said awesomeness). Tomorrow night I get to work on using add-on cards. Word of advice: D13 is internally connected to an LED with inline resistor on the board. You don't need any extra stuff (LEDS, resistors, etc) in order to do a first program to make the D13 an output and toggle it high and low, and feel good that the board works. Similarly, a blinking D13 can prove that a program is running when it blinks on at the beginning of the loop() function and off in the midst of the loop() function. Word to the wise.

As far as the Arduino platform is concerned, it's great. Great idea, great design, generally quality stuff. If it helps you, the Amazon shopper looking for a genuine UNO, I ordered mine from CanaKit and it is the genuine artifact, not a clone (fast shipping too!). There is one problem though and that is that these little boards (clone or original) are fairly easy to destroy (i.e. short circuit). I don't understand (well, I gue$$ I do) why someone who is making a product supposedly intended for students, artists and creative types doesn't put more protection on these things. After I fried my second UNO for a reason that was not clear to me at the time, I searched and found the Ruggeduino. Same stuff and though it's not "genuine" and costs a little less than twice as much, it has resettable fuses on every I/O port and then some, and it's made in the US! No, you're not exactly funding the Arduino project, but if that really appeals to you, I'm sure you can just donate money to them. Look it up if you are interested in Arduino, but have fat fingers or are sometimes clumsy with your circuits or just want to have the ability to make a mistake and not be fined for it. To me, Ruggeduino is what Arduino should have been from the beginning. Something that prevents you from making $20 mistakes because your lazy, ignorant, impatient or just plain stupid.

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.

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.
