Arduino is an open-source physical computing platform based on a simple I/O board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing and MaxMSP). The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free at https://arduino.cc

Bug reports and technical discussions
To report a bug in the software or to request a simple enhancement go to Github Issues
More complex requests and technical discussion should go on the Arduino Developers mailing list
If you're interested in modifying or extending the Arduino software, we strongly suggest discussing your ideas on the Developers mailing list before starting to work on them. That way you can coordinate with the Arduino Team and others, giving your work a higher chance of being integrated into the official release
