INO file extension - Arduino sketch

What is ino file? How to open ino files?

File type specification:

Source code and script file type icon Source code and script file type

File extension ino is associated with the Arduino, an application that allows users to develop applications for Arduino open-source electronics prototyping platform.

These ino files store source code written in Arduino programming language and used on Arduino circuit boards replacing the previously used .pde files.

The Arduino software program is an electronics prototyping platform with source codes written in the Arduino programming language.

Arduino sketches

Sketchbook is where program code files are stored. Arduino sketches are saved as .ino files and must be stored in a folder with the exact name. For example, a sketch named my_sketchname.ino must be stored in a folder named my_sketchname.

Typically, your sketches are saved in a folder named Arduino in your Documents folder. To access your sketchbook, click on the folder icon in the Arduino IDE's sidebar.
