This article explores gamification as a pedagogical strategy in education by presenting the development of an automated tic-tac-toe board based on a CNC pen plotter. The system was designed to function using NEMA 17 stepper motors, A4988 motor drivers, an Arduino UNO, and reed switch sensors (magnetic sensors), enabling students to program the CNC movements and interact with their moves in an automated manner. The aim of this work is to integrate concepts from electronics, programming, and mechanics to create an interactive environment that promotes practical and interdisciplinary learning.

The project adopts the STEM approach (Science, Technology, Engineering, and Mathematics), which encourages participants to apply theoretical concepts to real-world situations by integrating multiple disciplines to foster practical and interdisciplinary learning. Developed in a digital fabrication laboratory, the project directly applies technologies for rapid prototyping and idea customization, highlighting the gamification process through the increased focus and dedication observed during its implementation. Consequently, participants acquire significant knowledge in automation, programming, and electronics.

This work underscores the potential of gamification in making technical learning more dynamic and accessible, while also encouraging problem-solving, critical thinking, and creativity. It demonstrates how learning can become intuitive, with students developing skills and knowledge by gamifying real-world projects of personal interest, thereby attracting more learners to technology fields. The study concludes that the application of gamified tools and the STEM approach, such as the automated board, can positively impact learning outcomes.
