Environment Environment-Toolbar Buttons The toolbar buttons allow you to run and stop programs, create new sketches, open, save and export: Run Compiles the code, opens a display window, and runs the program inside Stop Terminates a running program, but does not close the display window New Creates a new sketch Open Provides a menu with options to open files Another way of opening files is dragging and the file icon to text editor area or processing icon Save Saves the current sketch to its current location Export Exports the current sketch as a Java applet embedded in an HTML file Your First Piece of Code void setup(){ size(200,200); } void draw(){ background(125); float x=mouseX; float y=mouseY; println("Mouse x=" + x + " Mouse y=" + y); line (x,y,100,100); } Environment-Menu Bar The menus provide the same functionality as the tool bar in addition to actions for file management and opening reference materials Environment-Menu Bar-Default Examples Under Examples you can find already made codes that you can use as the base of your experiments and achieve the desired result by changing these base codes This is what programmers call hacking Meaning that you not start a piece of software yourself You use other’s software and change parts of it, to make it work your way Hacking the Default Examples For example lets go to examples , under basic, under transform, choose arm, and run the code Hacking the Default Examples Let’s say we want the background color white and we want to double the size of the applet Hacking the Default Examples size(400,400); Hacking the Default Examples background(255); Hacking the Default Examples Your code Preexisting Code Hacking the code Tele-presence – Connecting Two Processing Platforms via Internet Controlling Arduino Output based on Distant Arduino Input 10 Tele-presence – Connecting Two Processing Platforms via Internet Controlling Arduino Output based on Distant Arduino Input 11 Tele-presence – Connecting Two Processing Platforms via Internet Controlling Arduino Output based on Distant Arduino Input 12 Tele-presence – Connecting Two Processing Platforms via Internet Controlling Arduino Output based on Distant Arduino Input 13 Tele-presence – Connecting Two Processing Platforms via Internet Controlling Arduino Output based on Distant Arduino Input 14 Tele-presence – Connecting Two Processing Platforms via Internet Controlling Arduino Output based on Distant Arduino Input 15 Tele-presence – Connecting Two Processing Platforms via Internet Controlling Arduino Output based on Distant Arduino Input First Arduino Connects to The first Processing Using Serial Port Serial.begin(9600);//Open Serial Port Serial.println(in);//Sending Data via Serial Port First Processing Function as a Server Connecting To the Second Processing via Net, Reading Data from Arduino Using Serial Port and Sending Data to Client Processing Using Net import processing.net.*;//Importing the net library to Connect to Second Processing and Send Data to it import processing.serial.*;//Importing serial Library to Connect to Arduino and Read from It Server myServer;//Initiating a Server to Send data to Client via net Serial port;//Initiating a Serial Port to Receive Data from Arduino myServer = new Server(this, InternetPort);
