Download the Arduino Software
The open-source Arduino environment makes it easy to write code and upload it to the i/o board. It runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing, avr-gcc, and other open source software.
Source Code
The source code to the Arduino software can be browsed online or checked out. See the instructions for building the code.

Serial Proxy
Also useful is the serial proxy for talking to an Arduino board from Flash or other programs. It forwards data from a serial port to a network connection and vise-versa. Download: Mac, Windows, source
