Contributed to the UFABCRocketDesign/newbie_software repository by developing two features focused on embedded systems and IoT using Arduino and C++. The work included implementing LED blinking functionality compatible across various Arduino boards by utilizing the built-in LED on pin 13, as well as integrating a BMP085 sensor to enable real-time sensor data acquisition alongside LED control. The code was organized into modular functions for LED blinking and sensor reading, with serial output to enhance observability. These enhancements improved hardware compatibility and maintainability, streamlining hardware validation and making it easier for new contributors to onboard and test hardware demos.
