Our second project involved using a Circuit Playground Express (CPX) to bring "My Magic Puppy" to life, responding to loud sounds with a magical reaction. This project emphasized themes of responsiveness, interaction, and meticulous testing. At each step, I recognized the importance of continually testing whether elements like color, wait time, and the layout of fairy light strands met our expectations. This iterative approach—refining details to achieve the desired effect—transformed challenges into learning moments, building my confidence and reinforcing the value of patience and precision in programming. Through this project, I learned how rigorous testing can shape creativity and bring ideas to life.
