Note: Special price while stock lasts. The new Arduino Uno replaces the Duemilanove and is 100% compatible.Description: 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, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
A great description of the new functionality can be found here (USB fuse protection, software reset, and much more!). Board comes fully assembled and tested with ATMega328 pre-loaded with bootloader. Please see the Arduino support forum for more information about this new board revision and bootloader. This new chip doubles the amount of Flash memory to 32Kb and the amount of available RAM to 2Kb. Just imagine what you can do with so much memory!!!
We also recommend the Arduino Protoshield Kit to use with your new Arduino. This kit offers a easy way to prototype your first Arduino projects, in a very compact form.
