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). Arduino is an open source project, owned by nobody and supported by many. For more information, see the website at: http://www.arduino.cc/ or the forums at http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl The Team is composed of Massimo Banzi, David Cuartielles, Tom Igoe, David A. Mellis and Nicholas Zambetti. Gianluca Martino works with us on many projects providing help, ideas and taking care of the production. Yaniv Steiner and Giorgio Olivero have been supporting the project and are working at using it with the Instant Soup platform. Arduino uses the GNU avr-gcc toolchain, uisp, avr-libc, avrlib, and code from Processing and Wiring. INSTALLATION Detailed instructions are in reference/howto.html. If you are using a USB Arduino, you will need to install the drivers for the FTDI chip on the board. These can be found in the drivers/ directory. On Windows, you will need to unzip FTDI USB Drivers.zip. Then plug in the Arduino board and point the Windows Add Hardware wizard to the FTDI USB Drivers directory. On the Mac, mount the FTDIUSBSerialDriver_v2_0_1.dmg disk image and run the included FTDIUSBSerialDriver.pkg. Also, on the Mac, run the macosx_setup.command (after moving the Arduino distribution to your /Applications folder). It corrects permission on a few files for use with the serial port and will prompt you for your password. You may need to reboot after running this script. UPDATES 0004 - 2006.04.26 Main sketch is now compiled as C++ (instead of C). Updated avr toolchain. printInteger(), printHex(), etc. now handle longs. millis() fixed (now overflows after days, not minutes) Fixed path to java in Windows run.bat. Added Matrix and Sprite libraries (written with Nicholas Zambetti). PWM now working on pin 11 (in addition to pins 9 and 10). Slowed PWM frequency (on all three PWM pins) to 1KHz. Now give an error if compiled sketch is too big. Fixed abs(), min(), max(), and constrain() macros. Added menu items to the IDE to burn bootloader. Now display binary sketch size on upload, and give error if too big. Added C++ serial library. Resynced with Processing/Wiring IDE code (improved auto-format, faster logging to serial monitor console, other bug fixes) New library system. Updated to latest version of the RXTX serial library; Mac users will need to rerun macosx_setup.command. 0003 - 2006.01.16 API Changes Reversed the analog input pins to correspond to newer boards. This means a call, for example, to analogRead(0) must be changed to analogRead(5) in order to read the same physical pin. Added a printNewline() function (which sends '\n' = ASCII 10). New Stuff Reference is included (features native to C not yet documented). Serial monitor added (click the toolbar button to turn it on or off). Baud rate is controlled by the Serial Monitor Baud Rate Menu, defaults to 9600. Icon and implementation from Wiring. Serial port menu now automatically refreshes when opened. New blue color scheme and icons courtesy of Noah Shibley (colors are hardcoded into the source to ensure consistency with image files). Keyspan and FTDI USB drivers included with Mac and Windows distributions. Bug Fixes millis() now updates every millisecond instead of every second. Bootloader included with Windows distribution (it was already in the Mac dist). Updated icon of the Windows executable. Now flushing the serial port before uploading (should fix some errors). Improved accuracy of the delayMicroseconds() function. Other Upload rate no longer selectable from a menu within the IDE. Instead, edit the serial.download_rate item in the preferences.txt file. Created Xcode project for building Arduino on the Mac (doesn't yet regenerate the grammar files or package the distribution); active target should be "App". Removed unused or unimplemented items from menus. 0002 - 2005.10.05 New build process no longer uses makefiles; now controlled by preferences.txt. core/ replaced with targets/; can now link against Wiring libraries. Replaced print() with printString, printInteger, printHex, printByte, etc. Added menu for selecting serial port speed. Updated icon. Bootloader shrunk to less than 1 KB; fuses updated accordingly. Added serialRead(), serialAvailable(), and delayMicroseconds(). 0001 - 2005.08.25 This is the first released of the unified IDE + language library it's a terrible hack... but it works. at the moment it's in alpha stage but it can be used to work. The processing preprocessor is included but not used.
