Review: Nice Little Multitasking Board - I love this little machine. You can use it for a range of different tasks, from simple light blinks to complex timed sequences. While I haven't had the equipment to make elaborate projects with it so far, many people have used it to improve their everyday life, such as using it as an automatic plant waterer or pairing it with an RC522 Module to use it as an RFID door lock. The arduino itself is very easy to setup and use, as there are many useful videos online which give you tutorials on how to get started, and the actual Arduino IDE is incredibly beginner-friendly and even runs on Operating Systems such as Ubuntu and Kali (which can't be said for other IDEs...)! It is a bit annoying that the REV3 uses a slightly outdated USB for its power and data, but it's not too much of a bother. The pins on the Arduino are very easy to use and the actual Arduino is presented beautifully. As I said, I haven't gotten to the point of doing very difficult tasks with it, but it has worked nearly flawlessly for the stuff that I have done with it. It has a decent chunk of memory for tasks and runs pretty damn fast. Overall, this is a great computer-ette which boasts a very beginner-friendly community and software, and is very nice to use.
Review: Arduino Uno: The best starter board (ever!!) - I’ve been using the Arduino Uno for a while, and I think it’s fair to review it now. Here we go: Why I Love It: 1) Super Easy to Get Started – I was up and running in no time, even as a beginner. The Arduino IDE is simple, and there are endless (literally!) tutorials to follow online. 2) Huge Community Support – Anytime I hit a roadblock, I found a solution online. The community is massive, and that makes troubleshooting way easier. 3) Endless Possibilities – I’ve built everything from simple LED animations to a real-time dashboard for sensor readings. The fact that you can combine hardware and software so effortlessly is what makes this so exciting. A Few Downsides: 1) No Built-in WiFi or Bluetooth – I had to get extra modules for that, but honestly, at this price, I can't complain. 2) Limited Memory – It’s great for small to mid-sized projects, but if you're doing something complex with a ton of data, you might need a bigger board like the Arduino Mega. Final Thoughts: If you're into DIY, electronics, coding, or just love building stuff, the Arduino Uno is a must-have. And if you pair it with Processing (free GUI gui software) , like I did, you can build some seriously cool projects. Highly recommend!

## Questions & Answers

**Q: Do I need to buy usb cable seperately?**
A: Yes,you need,the USB cable is not included.Many thank and best regards.Pinto Elettronica Italia

**Q: With the Arduino Uno R3 connected to a PC VIA USB will I be able to read/write to the i/o lines from the PC?**
A: Yes provided you download Arduino IDE.

**Q: Does it have built-in wifi?**
A: Hi there, no, the uno would require a WiFi sheild attaching to it.

Hope that helps

**Q: hello, can you confirm that these are original Arduino products and that they have "made in italy" not "designed in italy" on the board? many thanks**
A: Hi Sud,Glad to be of help. The Arduino UNO R3 I ordered back in January of this year does have "made in italy" on it. It also came with what I believe was the correct packaging and I believe it to be genuine. However, I went back to check my review and see that the UNO offered now is £11-55 against the £21-01 I paid and I see that the supplier is different. Now a bargain is one thing but I think that around £20 or so is the going rate for a genuine UNO and I suspect that for £11-55 you may get a clone. I notice that the page does not claim to offer a genuine UNO. Searching amazon for "UNO R3" I found a model claiming to be genuine for £21-89 and I think this may be what you are looking for. I would add that I have a genuine UNO R3 so that I can test stuff that I can put on my website using this as the "reference" arduino design, but I do also use cheaper clones but only after using the genuine model as a prototyping board. It may be a bit naughty of amazon to change the supplier like this and leave the reviews in place. Hope this helps, please ask any other questions you may have.Regards,EddieB.

### ⭐⭐⭐⭐⭐ Essentially a mini computer
*by M***Z on 12 November 2025*

Very easy to use microcontroller that is compatible with almost every component in electronics. This is essentially a mini computer with very open capabilities in terms of what u can create with this. It's made out of strong materials so it won't just break randomly if you drop it and for the price it is great. If you choose to add LCD 16x2's which display stuff, the quality is really good and you can read the content off of them very clearly.
