During April 2026, contributed to the arduino/library-registry repository by developing and submitting three new Arduino libraries focused on matrix button interfaces, RS485 communication, and FRAM memory support. The work centered on expanding hardware integration options for embedded systems developers, streamlining the process of connecting matrix buttons, serial devices, and non-volatile memory modules. Using skills in Arduino, embedded systems, and library development, the libraries were designed to reduce setup complexity and improve discoverability within the Arduino ecosystem. No bug fixes were reported during this period, with efforts concentrated on feature delivery and enhancing the breadth of available resources for hardware projects.
