Installing the Drivers for Older Arduino Boards
Driver installation for older boards like the Duemilanove, Diecimila, or Nano
is a bit different. Still, you have to plug in the board first.
On Windows Vista, driver installation usually happens automatically. Lean
back and watch the hardware wizard’s messages pass by until it says you
can use the newly installed USB hardware.
Windows 8.x, Windows 7, and Windows XP may not find the drivers on
Microsoft’s update sites automatically. Sooner or later, the hardware wizard
asks you for the path to the right drivers after you have told it to skip auto-
matic driver installation from the Internet. Depending on your Arduino board,
you have to point it to the right location in the Arduino installation directo-
ry—that is the
drivers/FTDI USB Drivers
directory.
After the drivers have been installed, you can start the
Arduino
executable from
the archive’s main directory by double-clicking it.
Please note that the USB drivers don’t change as often as the Arduino IDE.
Whenever you install a new version of the IDE, check whether you have to
install new drivers, too. Usually it isn’t necessary.
Installing the Arduino IDE on Mac OS X
The Arduino IDE is available as a zip file for Mac OS X.

The IDE depends
on the Java Virtual Machine, and at the time of this writing it’s available for
Java 6 (recommended) and Java 7 (experimental). Download it, double-click
it, and drag the Arduino icon to your
Applications
folder. If you hadn’t installed
Java already, Mac OS X will ask you for permission to install it.
If you’re using an Arduino Uno or an Arduino Mega 2560, you are done and
can start the IDE. Before you can use the IDE with an older Arduino, such
as the Duemilanove, Diecimila, or Nano, you have to install drivers for the
Arduino’s serial port. You can find the latest version online.

Download the
package for your platform (it usually has a name such as
FTDIUSBSerialDriv-
er_10_4_10_5_10_6.mpkg
), double-click it, and follow the installation instructions
on the screen.
When installing a new version of the Arduino IDE, you usually don’t have to
install the drivers again (only when more recent drivers are available).
