Arduino 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.

Honestly, my nephew asked for this for Christmas and I don't know what it is. But, he picked it out and put it on his wish list. When he opened it, two of my other nephews said it was cool....smh, I had to ask. They explained and said it was a necessary microcontroller for something. I stopped listening 😁. But they all told me it was a good thing. I asked my nephew before this review how well it worked, and he said he is still using it and it was fairly easy to install. He said it is doing exactly what it is supposed to do with no issues at all. So, I am not sure if my review helps anyone, but know tha5 he is one satisfied customer.

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.

Excited to use this to further advance my skills with microcontrolling for my major! Gave 4 stars because my Arduino Uno did not come with its usb cable unless I misunderstood the packaging.

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!

I did some project work for a local haunted house, and they were trying to get some $150 input-USB board working. It would be used to read switches from pressure mats, and turn that in to signals that the computer could read. Time was running out, and we had two of these things ($300 down the drain) we could not get to work. Thanks to exposure to an Arduino at my day job, I went down to the local Radio Shack and picked up an Arduino Uno R3. Within the hour, I had figured out that it was a matter of hooking up some wires and writing a few lines of simple C-like code to do what I wanted. Over the next week, I did more playing and learned how to read analog light sensors and buttons as well. I ordered a second one from Amazon and we used two of them in two different attractions. It was quite the learning process, and I see all kinds of applications for these mini computers. I wish I had learned about them years earlier! This device is a joy to work with! The Arduino site is full of documentation, example programs, and software to build on Windows, Mac or Linux. It's a great device for all kinds of projects -- blinking lights, counting, controlling devices, etc. I am totally sold on how easy it was to get going -- and since it's currently available at Radio Shack, if you use it for anything mission critical and cannot get a replacement in time via Amazon Prime 2nd day delivery, you can walk in to a local store and pick one up (though at a much higher cost). Nice I haven't had this much fun toying with a computer since the 80s 8-bit home machines that we hooked up to TV sets.
