Arduino IDE vs IntelliJ IDEA

Arduino IDE is an open-source integrated development environment for writing, compiling, and uploading code to Arduino microcontroller boards. It supports C/C++ programming with a simplified API and includes a serial monitor for debugging.

IntelliJ IDEA is full-featured Java and Kotlin IDE with deep code analysis, refactoring tools, and framework-specific support. It provides comprehensive features for code-editors workflows. The tool is actively maintained with regular updates and strong community/vendor support.
