> 3 day$35 Leonardo board. Its a great board, no complaints, but if I had to do it over again, Id but the $25 UNO board.

> 3 dayWow the most advanced Serial EVER !!, really is the new way for using serial data in the arduino, I worked with Decimilia and clones, the serial direct. This affected me because of old code I wrote and use from the web. So now I stumble with a RX LED Fixed and non-responsive Leonardo. But just check the literature in arduino.cc Leonardo and worked just fine.

> 3 dayIn my case, my arduino has come up with a problem (he has a problem when loading a project) but it is a problem that can be solved, so I put 3 stars and not 5.

Greater than one weekThis device completely met my expectations... Only thing I would complain about is the shipping time, but I think that would be due to the weather at the time. Only reason I gave it 4 stars instead of 5 is that the headers were soldered on crooked (about 70 degree angle instead of 90) and thats a little annoying, but other than that its perfectly what I expected.

> 3 dayGenuine Arduino shipped, but never connected through USB (on board programmer issues). Had to use ICSP headers and a separate programmer in AVR Studio to get code onto it.

Greater than one weekI built an MDF DDR board with this as the brain. It was a super fun project and the fact someone already had coding built for the button mapping made things that much easier!
ABOUT ARDUINO
Arduino is the world’s leading open-source hardware and software ecosystem. The Company offers a range of software tools, hardware platforms and documentation enabling almost anybody to be creative with technology.
Originally started as a research project by Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis at the Interaction Design Institute of Ivrea in the early 2000s, it builds upon the Processing project, a language for learning how to code within the context of the visual arts developed by Casey Reas and Ben Fry as well as a thesis project by Hernando Barragan about the Wiring board.
WHY ARDUINO?

|
|
|---|---|---|---|
InexpensiveArduino boards are relatively inexpensive compared to other microcontroller platforms. The least expensive version of the Arduino module can be assembled by hand, and even the pre-assembled Arduino modules cost not so high. |
Simple, clear programming environmentThe Arduino Software (IDE) is easy-to-use for beginners, yet flexible enough for advanced users to take advantage of as well. For teachers, it"s conveniently based on the Processing programming environment, so students learning to program in that environment will be familiar with how the Arduino IDE works. |
Open source and extensible softwareThe Arduino software is published as open source tools, available for extension by experienced programmers. The language can be expanded through C++ libraries, and people wanting to understand the technical details can make the leap from Arduino to the AVR C programming language on which it"s based. Similarly, you can add AVR-C code directly into your Arduino programs if you want to. |
Open source and extensible hardwareThe plans of the Arduino boards are published under a Creative Commons license, so experienced circuit designers can make their own version of the module, extending it and improving it. Even relatively inexperienced users can build the breadboard version of the module in order to understand how it works and save money. |
ARDUINO CLASSICS
Message from Massimo Banzi - co-founder
“The Arduino philosophy is based on making designs rather than talking about them. It is a constant search for faster and more powerful ways to build better prototypes. We have explored many prototyping techniques and developed ways of thinking with our hands.”

ARDUINO CREATE
Connect, Create, Collaborate
Arduino Create is an integrated online platform that enables Makers and Professional Developers to write code, access content, configure boards, and share projects. Go from an idea to finished IoT project quicker than ever before. With Arduino Create you can use an online IDE, connect multiple devices with the Arduino IoT Cloud, browse a collection of projects on Arduino Project Hub, and connect remotely to your boards with Arduino Device Manager. As well you can share your creations, along with step-by-step guides, schematics, references, and receive feedback from others.
