> 3 dayDelivery was great...like one day after I placed the order. The order was for an Arduino, a sensor kit, and a camera. Everything was there, but the Arduino package had been opened...the tape at the top was torn off and the box was coming apart. I had the feeling it was something someone else returned. Ill test it in a couple days and return it if anything seems to be not working.

> 3 dayThis Arduino UNO Rev 3 appears to be 100% compatible with UNOs I have previously purchased a year or two ago. My sketches that I previous created uploaded and ran on the first attempt on these newer boards. The board components and layout look nearly identical to what I previous bought. The biggest difference is the PCB is green and not blue, and there is now labeling on the side of the pins, which is useful. Also, the new board is mounted on a clear plastic base. For me, paying a little extra to ensure I get a real Arduino is worth it.

07-06-2025If youre creating how-to instructions for people to follow regarding this device, you will need to update it every time they update something on this product. The IDE sometimes becomes updated, so software installation instructions may change. The libraries (like SoftwareSerial) sometimes change and things like older versions of grove LCD screens can suddenly become unusable.

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.”
