Greater than one weekGreat board that is the core of my multi-board project. Was able to reduce power consumption with careful code to less than 8 milliamps, and with my solar powered battery it should be able to run forever without replacing batteries. The Leonardo was the best at power savings compared to several other Arduinos that I tried including the Uno, Nano, and Mega.

> 3 dayThis is an authentic Arduino. I was concerned because it was priced lower than most other vendors, but it is truly authentic and a quality product.

Greater than one weekWell in truth theres only one uart but has a virtual serial port (usb) thats infinitely useful in debugging apps where the uart serial is in use. I will be buying Leonardos from now on or perhaps the mega clones from China which even lower cost.

Greater than one weekUsed this little board to build a process controller. Easy to implement in a chassis with all the other components. Only downside is the headers are not quite as secure as desired.

> 3 dayBeing a PIC guy I thought I would never buy an Arduino. But the thing is: it is ready. Nothing to design, etch or solder. It simplifies most of your problems... If you need something more from your boards, design one using a PIC24. If you`re considering using something simpler, stick to the arduino.

> 3 daythis is the real arduino, the best thing about it is that it connect to the computer via a micro usb cable witch is the most common usb cable, and its the same size of the arduino uno so all uno shield would fit on this leonardo.....

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.
