Oscar Bryan Magtibay developed and maintained hardware interaction features for the oscarbryan-magtibay/embeddedcpe4A2526 repository, focusing on servo motor control for Activity 3. He implemented initialization routines and serial input handling in C++ to enable precise 0-180 degree servo movement, incorporating basic input validation to ensure reliable operation. After delivering the initial feature, he deprecated and removed the servo control code to streamline the codebase and reduce future maintenance risks. His work demonstrated practical application of Arduino, embedded systems, and microcontroller skills, with an emphasis on codebase hygiene and clear project direction rather than extensive bug fixing or feature expansion.
