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.

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.

TUDO OK COM O ITEM

Werkt goed, op Windows 11 64bits.

ATML iC programbel chep , it’s all about it, green or blue, doesn’t mean anything Bay it as it’s ATML

Ok

Pros. Good quality Cons. None
