Install the software
Before connecting the Arduino module to your computer, download the Arduino software
If you're using Windows, double-click the installer you just downloaded to install the Arduino software. Proceed through the installation process. Now, navigate to the following folder on your computer:C:\Program Files (x86)\Arduino\drivers
Double-click on "dpinst-x86.exe" or "dpinst-amd64.exe" depending on if you have a 32-bit or 64-bit version of Windows respectively. This application will install drivers for your Arduino to communicate with your computer.
If you're running the Mac OS, unzip the downloaded file and move the Arduino application to your "Applications" folder to install the Arduino software.
You will also need to download the Processing software
If you're using Windows, unzip the downloaded file. This will provide you with a folder with a name like "processing-2.2.1". Inside this folder is a file named "processing.exe". This is your Processing application.
If you're using the Mac OS, unzip the downloaded file and move the Processing application to your "Applications" folder to install the Processing software.Download the sketches
Above in the "Other files" section of this project are two files. Downloaded these files. "Analog Pong - Arduino" is the sketch for your Arduino module and "Analog Pong - Processing" is a collection of files that make up your sketch for the desktop software written in Processing.
First, download "Analog Pong - Arduino". This will provide you with a single file named "analog_pong_arduino.ino". Double-click this file and Arduino should open and prompt you asking to move this sketch to its own project folder, click OK. The Arduino software should now be on your screen displaying the pong sketch for your Arduino module.
Second, download "Analog Pong - Processing". This will provide you with a zip archive named "analog_pong_processing.zip". Unzip this archive. Return to the location of your Processing application and run it. Go to the menu at the top and click File > Open... Navigate to the location of your Processing sketch folder "analog_pong_processing" then select "analog_pong_processing.pde" and click Open.
You should now have both your Arduino software open with the Arduino Pong sketch and the Processing software open with the Processing Pong sketch.
