Emilly Mariane developed two features for the UFABCRocketDesign/newbie_software repository, focusing on embedded systems and IoT using Arduino and C++. She implemented cross-board compatible LED blinking by leveraging the built-in LED on pin 13, ensuring consistent behavior across different Arduino models. Emilly also integrated BMP085 sensor readings, structuring the code with modular functions that separately handle LED blinking and sensor data acquisition, with serial output for observed values. This approach improved code maintainability and observability, streamlining hardware validation and onboarding for new contributors. Her work demonstrated a clear understanding of hardware-software integration and modular embedded software design principles.
