This tag is for questions about the official Arduino IDE. This open-source IDE makes it easy to write code/sketches and upload it/them to any Arduino board. The IDE runs on Windows, macOS and Linux.

Virtually all beginner tutorials use the Arduino IDE. You can write the code, select the correct COM port, and then click "upload." Other IDEs may require more configuration and not be as user friendly. It is available as a standalone application or installer on Windows.

Arduino IDE running on Ubuntu Linux.

For more information about Integrated Development Environments in general, see the tag.

What are the other IDEs for Arduino?

The basic Arduino IDE lacks a lot of the sophistication present in other IDEs such as code completion, code collapsing, folder organisation, etc. Are there other IDEs that allow programming in C or C++ and improve on these aspects?

ESP8266, Arduino IDE vs Lua?

I'm planning to buy an ESP8266. Do I really need to learn Lua to play with it? I have seen some people using it with the standard Arduino IDE. Do you need a custom firmware to use the Arduino IDE instead of Lua? The Arduino IDE seems better for me…
