About Ardulink-2
Ardulink-2 is the evolution of the original Ardulink project — a complete, open source, Java solution for the control and coordination of Arduino boards.
History
The original Ardulink project provided a Java-to-Arduino communication framework. Ardulink-2 was rebuilt from the ground up with a modular architecture, separating the core protocol from transport-specific link adapters.

Architecture
Ardulink-2 is built as a modular Maven project. The core provides the Link interface and pin abstraction, while link adapters implement specific transport protocols.
