Worked on the TeamXbot2025 repository to deliver a hardware control feature enabling lights management through Digital Output (DIO) channels. Developed and integrated a LightSubsystem in Java, allowing set and get operations for light states, and implemented comprehensive test coverage to validate DIO control logic. Addressed a hardware configuration issue by correcting DIO mappings for the Algae Arm Bottom Sensor and multiple lights, ensuring accurate hardware assignments and reducing wiring risks. Focused on embedded systems and robotics, the work improved automation reliability and maintainability of the electrical subsystem, emphasizing robust hardware control and thorough validation to prevent future regressions.
