You can buy an Arduino board from the official store online or from one of the distributors listed on this page. If you’d prefer to build your own, see the Arduino Single-Sided Serial board, which can be easily etched and assembled.
If you’re creating tutorials, managing a local community of Arduino users, opening up an Arduino-focused page online (ie. social networks) you can use the Arduino Community Logo! This will allow people identify better what comes directly from us, and what comes from the community.
Yes, with the following conditions:
- Physically embedding an Arduino board inside a commercial product does not require you to disclose or open-source any information about its design.
- Deriving the design of a commercial product from the Eagle files for an Arduino board requires you to release the modified files under the same Creative Commons Attribution Share-Alike license. You may manufacture and sell the resulting product.
- Using the Arduino core and libraries for the firmware of a commercial product does not require you to release the source code for the firmware. The LGPL does, however, require you to make available object files that allow for the relinking of the firmware against updated versions of the Arduino core and libraries. Any modifications to the core and libraries must be released under the LGPL.
- The source code for the Arduino environment is covered by the GPL, which requires any modifications to be open-sourced under the same license. It does not prevent the sale of derivative software or its inclusion in commercial products.
In all cases, the exact requirements are determined by the applicable license. Additionally, see the previous question for information about the use of the name “Arduino”.
In fact, you already are; the Arduino language is merely a set of C/C++ functions that can be called from your code. Your sketch undergoes minor changes (e.g. automatic generation of function prototypes) and then is passed directly to a C/C++ compiler (avr-g++). All standard C and C++ constructs supported by avr-g++ should work in Arduino.
It is possible to compile programs for the Arduino using other build tools (e.g. Makefiles and/or AVR Studio). You’ll need to configure these to link against the appropriate files in the Arduino core libraries.
Sure. It’s just an AVR development board, you can use straight AVR C or C++ (with avr-gcc and avrdude or AVR Studio) to program it.
Yes, although it may require some modifications to the Arduino core libraries.
You can use for Ubuntu Linux, for Debian Linux, for Gentoo Linux, for Linux, or for Linux on PPC. You can use Arduino from the command line, and not have to install Java.
The reference designs for the Arduino boards are available from their specific product pages. They’re licensed under a Creative Commons Attribution Share-Alike license, so you are free to use and adapt them for your own needs without asking permission or paying a fee. If you’re looking to make something of interest to the community, we’d encourage you to discuss your ideas on the hardware development forum so that potential users can offer suggestions.
