Wiring is an open-source programming framework for microcontrollers.
Wiring allows writing cross-platform software to control devices attached to a wide range of microcontroller boards to create all kinds of creative coding, interactive objects, spaces or physical experiences. The framework is thoughtfully created with designers and artists in mind to encourage a community where beginners through experts from around the world share ideas, knowledge and their collective experience. There are thousands of students, artists, designers, researchers, and hobbyists who use Wiring for learning, prototyping, and finished professional work production.
