Arduino IDE is a desktop development environment for writing, compiling and uploading programs to Arduino and compatible microcontroller boards. It provides tools for developing embedded applications, from simple sensor projects to more complex electronic systems.
Programs, known as sketches, are written using a language based on C++. The IDE handles compilation and communication with connected hardware, allowing developers to work with supported boards without manually invoking separate development tools.
Its interface is built using Eclipse Theia and Electron, with compilation and upload operations handled by Arduino CLI. It is suitable for beginners learning electronics and experienced developers building microcontroller-based projects.
This is free and open source software.
Key Features
- Source code editor with syntax highlighting, intelligent code completion and contextual suggestions.
- Compile sketches and upload programs directly to supported Arduino and compatible boards.
- Board Manager for discovering and managing supported microcontroller platforms.
- Library Manager for finding, adding and maintaining reusable programming libraries.
- Integrated Serial Monitor for sending and receiving data through serial connections.
- Serial Plotter for visualising incoming numerical data as live graphs.
- Built-in debugging with breakpoints, variable inspection and step-by-step execution on supported boards and debugging hardware.
- Navigate project files, functions, variables and other code elements.
- Work with sketches containing multiple source files and editor tabs.
- Customisable automatic code formatting and indentation.
- Access example sketches supplied with the IDE and installed libraries.
- Select connected boards and communication ports from the development interface.
- Display compiler output, upload progress, errors and diagnostic messages.
- Manage firmware updates and certificates on supported connected hardware.
- Synchronise sketches with Arduino Cloud through the remote sketchbook functionality.
- Cross-platform support – runs on Linux, macOS, and Windows.
