Appendix A. Installing the Arduino IDE
This appendix details how to install the Arduino IDE on the Windows, Mac OS X, and Linux platforms. The Arduino IDE for all platforms is available from the Arduino website (http://arduino.cc/en/Main/Software). Download the IDE package for your platform and continue with the appropriate installation section for your operating system.
Arduino for Windows comes packaged as a zip file, so once it’s downloaded you must first extract its contents. Browse to where you downloaded the file (typically your User/Downloads folder) and double-click the zip file. As shown in figure A.1, extract or drag the containing folder to somewhere accessible on your hard drive, such as C:\Program Files.
