For your homework please create an interactive system consisting of Arduino-based hardware and Processing-based software. Use at least 3 hardware inputs in Arduino. Determine the usable ranges and send the data from your sensors to a Processing sketch via serial communication.
On the Processing side first ensure clean and stable serial communication and usable values. Then re-map the data you'll be getting from you sensors to some visual parameters in your sketch. Positions of objects, colors, sizes, speed of movements, etc - are all good examples of such parameters. Each parameter comes with it's own reasonable range so put some thought into a re-mapping process.
Experiment with the application of the 3 values we're getting from Arduino. See where you can plug them in to achieve interesting graphic results. Get creative by picking a theme or making an animated illustration - look at modern and contemporary art for inspiration.
Capture the results on video, upload zip files with your Arduino and Processing files along with the videos.
