Contributed to the d3moore2002/UCSD_BMES_PT_2024-25_HeartSim repository by developing and refining an Arduino-based heart simulation platform over four months. Delivered features including servo motor control for automated valve actuation, dynamic BPM selection, and a two-servo model simulating mitral and aortic valve dynamics. Employed C++ and embedded systems techniques to enable precise timing, real-time angle feedback, and flexible input handling using switch statements. Enhanced project documentation in Markdown to improve contributor onboarding and project sustainability. The work established a robust foundation for hardware-in-the-loop cardiac simulations, supporting reproducible experiments and facilitating future expansion of simulation complexity and hardware integration.

Apr 1, 2025April 2025: Delivered the initial heart valve servo motor control simulation in the UCSD BMES HeartSim project. Implemented a two-servo motor model to open and close mitral and aortic valves according to predefined timings and cycle length, establishing a functional valve dynamics prototype for downstream cardiac simulations and hardware testing. This milestone creates a foundation for integrating more complex valve kinematics and sensor feedback, enabling early validation and reducing hardware prototyping risk.
