I can't believe it took me so long to stumble onto this little gem. It's a great little microcontroller for all sorts of applications or projects. it is well-supported by online resources and documentation. It is easy to develop programs for it using the IDE which is freely available to download on the Arduino website.

Easy to setup and use

Reviewed in the United States on March 12, 2024

As someone who has used Raspberry Pis for past projects, this felt more purpose built to easily throw some code in it and have it just run.

The USB interface to the Arduino IDE sets up in less than a minute and makes deploying and updating code super easy. The built in connectors make wiring incredibly easy.

I bought two of these for home projects and couldn't be happier. These will be my go to going forward

Beware of Fake Arduini from Amazon! Mp3Car Rocks!

Reviewed in the United States on December 31, 2012

Verified Purchase

I ordered a second Arduino from Amazon in mid-December to supplement the first one I'd bought from them a few weeks earlier, and I got quite a shock when it arrived. The new Arduino was a fake!

This fake Arduino arrived in an antistatic-bag with a 2ft USB cable instead of the usual Arduino printed box with documentation. The screen printing on the front was OK, but the printing on the back was smudgy and blurry, and the soldering job was poor, obviously done by hand. Additionally, some of the components differed from those on the genuine Arduino.

I noticed several signs of inauthenticity, but three of the most telling were the following:

1) The L and ON LEDs on the fake Arduino were both red, instead of orange and green respectively on the genuine Arduino.
2) The reset button on the fake Arduino was chocolate brown, instead of red on the genuine Arduino.
3) The black-and-gold PTC resettable fuse from Bourns (501K) on the genuine Arduino (between the power jack and the USB jack) was replaced by a green PTC fuse from Raychem (5X5).

Since I had just purchased a genuine Arduino from NKC Electronics (fulfilled by Amazon), I knew exactly what to look for. However, this second Arduino was purchased from Mp3Car Store (fulfilled by Amazon), so I complained to Mp3Car.

Mp3Car explained that although they only ship genuine Italian-made Arduini to Amazon, Amazon does so-called “commingling” of inventory. So Amazon will take a random Arduino from their inventory and ship it to a customer instead of searching for one of the units send to them by the particular vendor (Mp3Car in this case). Since Amazon still had many fake Arduini in their inventory, I unfortunately received one of them.

Fortunately, Mp3Car Store stood fully behind their customer (me). When Amazon didn’t agree to ship me a genuine replacement right away, Stephen (Mp3Car store manager), and Rob (Mp3Car owner), immediately arranged to send me a genuine Arduino directly from their own stock, and it arrived the next day by UPS.

I now have another genuine Arduino Uno, and I’m eternally grateful to Mp3Car for facilitating it. I recommend the Arduino as an affordable platform for physical computing, and I highly recommend Mp3Car Store as a trustworthy vendor to purchase it from.

Works good so far

Reviewed in the United States on March 18, 2023

Size: Arduino Uno regularVerified Purchase

The media could not be loaded.

Have tested this microcontroller with driving motors and solenoid valves, and it works well with the L293 motor shield (which is why I got it). I think it is fairly priced for the level of quality, it seems quite well made. I just need to figure out how to use it outside of Arduinos IDE and then it will be perfect.

4/5 for me.
