What is a PDE file?

A PDE file is a software program created for use with Arduino, an open-source electronics prototyping platform. It contains source code written in the Arduino programming language. PDE files were used to control Arduino circuit boards, but have since been replaced by .INO files.

More Information

The Arduino electronics prototyping platform allows developers to create and install basic programs, called sketches, on a variety of specialized circuit boards. Sketches can perform simple functions, such as making an LED installed on a circuit board blink, or complex functions, such as transmitting data over the Internet. Developers create Arduino sketches in the Arduino Integrated Development Environment (IDE), which previously saved sketches as PDE files.

To avoid internal file association conflicts, Arduino began saving sketches as .INO files with the release of Arduino 1.0. The Arduino IDE can still open PDE files, but it now saves all sketches as INO files.

How to open a PDE file

PDE files are meant to be opened and edited in the Arduino Integrated Development Environment (cross-platform) To open a PDE file in Arduino, select File → Open from the program's menu bar.

Because PDE files are plain text files, you can also open them in any text editor, including:

Processing Development Environment Source Code File

Source code file written in the Processing programming language; may contain functions, variables, and other programming constructs; used for storing Processing programs, called "sketches," and running them within the Processing IDE; can be used for programming images, animations, and interactions.

More Information

Each PDE file is stored in its own folder when saved from the Processing IDE. It is saved with any other program assets, such as images. The project folder and PDE filename prefix have the same name. When the PDE file is run, it is opened in a Java display window, which renders and runs the resulting program.

Processing is commonly used in educational settings for teaching basic programming skills in a visual environment.
