“The Arduino IDE is the well-known software we all use to program our boards. Its development started in 2005 based on the graphical interface of the Processing project and has never stopped since. During these years, countless hours of development by the Arduino team with the help of a vibrant community made the Arduino IDE the de facto standard for electronics prototyping. Thanks to an extensible framework based on modular board support packages, the IDE supports more than 1,000 official and non-official boards; it’s translated in 66 languages, mentioned by more than 3,000 books, and is still growing: during the last year, it was downloaded more than 39 millions of times. More than ever.
First off, a big thank you to the Arduino community that makes development possible with donations and — even more important — by buying original Arduino boards: we use your money to pay the developers that work daily on the Arduino open source software for the benefit of everyone. Keep supporting our work!
The path from a simple IDE to an advanced IDE
While the Arduino IDE provides a simple and clear interface that is ideal for the novice users, the more advanced users often report that the editing capabilities are a bit limited compared to modern editors. This includes features like code indentation, block folding, auto-closing brackets, regular expression search and replace, comment toggling. In addition to this, many users have been asking for live debugging, i.e. the ability to run code on an attached board and stop it at a given line to check the contents of variables, memory and registers.
The IDE 1.x is developed in Java, and its monolithic codebase makes it difficult to implement such features. Java is also becoming an obsolete technology for desktop applications and is being phased out by newer operating systems and app stores, which forces us to spend time on working around compatibility issues.
In 2018, we started to refactor the toolchain by announcing a big game changer: arduino-cli, the Arduino command line tool written in Golang that exposes all the core functionalities of the IDE, providing advanced users with a flexible tool they can integrate into their professional IDE of choice. Since then, we maintain and improve arduino-cli on a daily basis (try it now if you haven’t!).
In 2019, we announced the alpha release of a new IDE built on top of arduino-cli and based on a modern software stack (Theia and Electron) under the code name of “Arduino Pro IDE” and we got a lot of positive feedback about it. 2020 has been a busy development year, and a dedicated team of developers has been working behind the scenes to bring the new IDE from a proof-of-concept to a fully functional tool.
The time has come: please welcome the Arduino IDE 2.0 (beta)
We’re pleased to announce that as of today the Arduino IDE 2.0 beta is available for download and its code repositories become open source. It carries a modern editor and provides a better overall user experience thanks to a responsive interface and faster compilation time. Don’t be afraid of trying it today: the upgrade will be frictionless as the interface will look very familiar. But let’s see some of the goodies you’ll find.”
