Page 3 of 16 Objectives: 1. Become familiar with the Processing graphical environment, Java language, and reference site. 2. Understand the basics of data communication between Arduino and Processing. 3. Create a simple interactive system using Arduino and Processing. Background: Background Processing is an open source programming language and integrated development environment (IDE) built for the electronic art, new media art, and visual design communities with the purpose of teaching the fundamentals of computer programming in a visual context, and to serve as the foundation for electronic sketchbooks. The user interface of Arduino IDE is very similar to the Processing IDE user interface. Casey Reas and Benjamin Fry, both formerly of the Aesthetics and Computation Group at the MIT Media Lab, were involved in the creation of Arduino IDE as well as Processing IDE. However, please note some major differences: • Arduino IDE allows you to program Arduino boards by using a simplified version of C/C++ language, and use and control physical objects such as sensors and motors. • Whereas, Processing IDE allows you to write PC applications using a simplified version of Java language, and lets you create and control virtual objects such as circles and spheres and many other 2D and 3D graphics and shapes. One of the stated aims of Processing is to act as a tool to get non-programmers started with programming, through the instant gratification of visual feedback. The Processing language builds on the Java language, but uses a simplified syntax and graphics-programming model. 4. Component / Equipment List: Arduino Microcontroller Potentiometer USB cable Jumper M/M Breadboard LED Resistor 220ohms

Page 4 of 16 5. Procedure: Analysis: 1. In a new Processing sketch, open the example MouseeCircle.pde code available in Lab- #.zip file. The MouseeCircle.pde code is shown on next page (inside the text box) for reference. 2. Run the code in Processing IDE. You should see a circle drawn inside a graphics window, that will follow the mouse pointer. 3. Go to Processing reference website and look for the following functions used in the code. size(255, 255); strokeWeight(10); framerate(16); background(100); fill(0, 121, 184); stroke(255); ellipse(X, Y, radius, radius); 4. For each of the functions shown above, copy the function description from the Reference web site and paste it inside a comment block /* … */ before each function. The purpose is to thoroughly understand how the function works. 5. Final code for Part A of the lab should include a comment for each function used in the code, indicating what each function does. 6. Save the final modified code in a file and include it in your report. 7. Take a screenshot of the graphics window with the circle, to include in the Measurements section of the lab report. Design:
