During April 2026, contributed to the arduino/library-registry repository by developing two new C++ libraries focused on embedded systems. The RotaryEncoder library was built to improve rotary encoder handling, streamlining integration for Arduino projects and expanding hardware support. Additionally, the CANduino library introduced a simple API for CANduinos, incorporating features such as filtering, interrupt handling, and sleep mode to facilitate robust communication in embedded applications. All changes were thoroughly documented with clear commit messages, supporting maintainability and onboarding. The work emphasized library development best practices, enabling faster development cycles and broader adoption within the Arduino ecosystem, though no bugs were addressed.
