It's not what I thought but it's a good board

I purchased this with the impression it was an authentic Uno. At unboxing I thought this was a well disguised knockoff. It's a different color, the silkscreen is different, etc. This is NOT an authentic Uno provided by arduino.cc. However, it does appear to be an authentic Uno provided by arduino.org. You are not contributing to the cause when buying this board. I wanted to give the seller 2 stars but after reviewing his ad again I realized he delivered exactly what he said he would. I got what I paid for. The build quality is in par with the blue .cc arduino and better than some knockoffs I have. Mine came with a nice plastic base to keep your bottom leads off the work surface so that's a plus. I haven't powered it up yet but I doubt I'll have any issues. I will note that you should have at least one socketed version. Many Uno clones are surface mount 328P's. If you don't have one or you are looking for your first Uno this isn't a bad one to have. I bought this one with the intent to program the Atmel and remove it for a project. Enjoy

A CS major's ultimate toy

The Arduino Uno is just awesome. As a computer science major, I have had so much fun tinkering with it and using it in various projects. The Uno is a great microcontroller to get if it is your first, or if you just need something expensive. Arduino comes with excellent open source software which you can use to write your code (in C++) and then have it compiled and uploaded to the Arduino. The program takes care of all the details for you, so that all you have to do, essentially, is write the code and upload it. I know for a fact that the software is available on Windows and Ubuntu (what I use). I imagine it is available for OS X as well but I would check that to make sure. There are quite literally countless things you can do with the Uno. It is simply a miniature computer, so you can use it for fun, educational projects (mainly what I do), or you can build something practical with it (use your imagination!). If you're a tinkerer and what to get some hands-on experience with programming and electronics, I'd definitely recommend the Arduino Uno.

Arduino UNO R3 is a cool micro-PLC

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.

Authentic Arduino Uno

I received this Arduino Uno from MDN® USA. This Arduino Uno is authentic. It is the new design (teal color). All silk screening is spot on and has quality components. The difference from traditional authentic Arduino Uno (which I have and is green/blue color mixture from Arduino.cc) is silk screening on header pins for easy identification when using shields, which is high quality screening. The header pin silk screening is value added in my opinion (see last sentence to know more). In addition, the Arduino Uno comes with a clear plastic base (quality) for the board to rest on surfaces without accidentally grounding/shorting pins on bottom of board. The clear plastic base has two screw holes for securely mounting to surface. The Arduino Uno board clicks into clear plastic base and is easy to remove without releasing unintentionally (i.e. positive hold). This Arduino Uno is derived from Arduino.org instead of Arduino.cc, which is splitting hairs and not going to elaborate.

Flashed Bootloader to Printer

I purchased from the “Arduino” seller which is shipped and sold by Amazon. With that said, I wouldn’t know the difference if this is a fake or not but it worked perfectly for my use case. I purchased one of these along with some DuPont cables to flash the bootloader to my Ender 3 3D printer so I could get aftermarket Unified firmware on my printer. I was able to do just that without any issues.

Terrific - And it's expandable in many ways. POWER my world.

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.

It works and genuine from mp3Car Store

I received my item today 08/23/2016, arrived on time. I ordered through mp3Car Store. I consider any arduino from arduino.cc or arduino.org genuine. Either one of those manufacturers supplies a good quality genuine arduino. Google the differences between the two, however you cannot go wrong with one from arduino.org supplied by mp3Car Store. Well packaged, and no sign of mishandling. Like a little kid I opened it up and started playing with it. ***attention** Item does not come with power cable. It is not my first arduino so I didn't read any manuals and had the IDE already. If you are new, read or watch manuals, and download the IDE, it's free. It works, it turns on and no problems so far. I wrote everything you need to know to make a well informed purchase as I appreciate when people leave good reviews. Pass it along

Good for code learning

I learned from years of owning a Raspberry Pi that you should always spend the extra money for the genuine original if you are just starting out on learning to use it. I have so far only used this one with LED bulbs so I could see my code in action. If you are experimenting in ways that might damage the board, you should invest in a cheap knockoff.

The Real Deal

When the world of Arduino was shown to me a few weeks ago, I was intrigued. After watching some Youtube videos, and reading online accounts, it became clear that the use of Arduino with various sensors could do some amazing things. The hidden "mad scientist" within me started to come out. Looking thru the Amazon reviews showed great ratings, BUT there were a few issues that popped up in some reviews. Some indicated that they received fake Arduinos. A few said there were some quality issues. Issue 1 - Fake Arduino? An online post suggested that the Amazon seller be cross checked with "approved" vendors as listed on the official Arduino web site. I purchased mine through Karlsson Robotics, and they are indicated as an approved Arduino "supplier". The first thing I did when receiving my Arduino is to check all the standards means of detecting a fake. Every item checked out, in particular the gold 504L device. I am 100% assured that this is a product from the factory in Italy. Issue 2 - Quality? The quality of the board, solder joints and devices appears to be just about perfect. There are no instances of incomplete or rough solder joints. Everything is soldered in a super smooth manner, probably from one of their production machines. It's an outstanding job. So far I've done a few operations with the board, and no issues have been observed. The board connected easily to the computer via an A-B USB cable (not included with the board). Bottom Line: Karlsson Robotics is a legit supplier, and they provided my Arduino board with zero issues. Highly recommended that you purchase though them. The Arduino board is top notch, and is ready to go out of the box.

From ignorant to inventor in one easy step!

Before I got this, I looked at anything electronic with the eyes of a caveman. Now I know it's not magic. While I can't compare the Arduino to any other microcontroller (or even any other Arduino besides the UNO), I can confidently tell you it was the easiest introduction I could have hoped for. Just lighting up an led BLEW MY MIND. That's the most basic thing you can do, and it's right there at your fingertips when you get one of these. So easy and so flexible. The headers are great for breadboarding or just sticking things in to experiment with. USB connection made it stupid easy to interface with my laptop and dig in. I've come to really appreciate the power options: The final project I ended up using my UNO for was an under-cabinet lighting system using an LED strip that required 12V, and it evolved into a PWM fan controller for cooling some components inside the cabinet. Simultaneously! Just calculated the total current needed for the LED strip and the fans, plugged a 12V adapter with the calculated amperage into the barrel jack, BOOM. Oh, and I used a Frankenstein-style knife switch to control the lights using 5V so the switch looks dangerous but isn't. And a temperature sensor to turn the fans on and adjust the speed according to the temp. And an analog volt meter to show me how fast the fans are going. The learning curve was INSANE, I learned how to do all of this stuff in weeks. Support for the UNO is ubiquitous. Got a really cool case GeauxRobot Arduino UNO R3 Enclosure Case Clear. I know the Raspberry Pi is trendier now. I know there are dozens of Arduino variations, hundreds if you get a clone (although I can't praise the company highly enough and passionately support them - can't speak to whether this particular UNO is counterfeit, I just don't know enough yet). I DO know that the UNO turned a monkey into a man. I originally bought this 4 years ago, played around with it, learned a TON, and eventually decided on a project. I just bought two Nanos Mini Nano V3.0 ATmega328P Microcontroller Board w/USB Cable For Arduino I can't wait to come up with a project for. To be candid, it's still pretty magical to me four years later!
