Arduino IDE v2

Arduino IDE v2 is the development environment for writing, compiling, and uploading sketches to Arduino-compatible microcontroller boards. It combines a code editor with a toolchain wrapper, so a sketch written in the Arduino dialect of C++ is compiled and flashed to a connected board through a single interface. Board definitions and third-party libraries are installed from within the application rather than assembled by hand.

The second generation of the IDE adds editor features common to modern code tools, including autocompletion and symbol navigation, along with a debugger for boards whose hardware supports it. A serial monitor and serial plotter read data coming back from the board over USB, which covers most sensor and prototyping work without a separate terminal program.

This entry covers the Linux build, published by Arduino SA under the AGPL-3.0. The application depends on a physically connected board for uploading and debugging; the editor and compiler can be used on their own, but the rest of the workflow assumes hardware on the other end of the cable.
