A Digital Circuits project developed for the Digital Circuits course in the Computer Science program at Federal University of Cariri (UFCA).
Design and implement a digital game simulation using Logisim ITA, where a joystick controls a point in a 15x15 LED matrix, with the current coordinates displayed in 7-segment displays.
- Logisim ITA: Digital logic simulator
- Combinational logic (Demultiplexers, Binary to 7-segment converters, Logic gates)
- Karnaugh Maps (for logic simplification)
- The player uses a digital joystick (with 4-bit X and Y outputs) to move a point (a lit LED) across a 15x15 matrix.
- The X and Y coordinates of the active LED are converted from binary to decimal and displayed using four 7-segment displays (two for X and two for Y).
- The system ensures smooth and precise movement, allowing only one LED to be lit at a time.
- Demux Y: Takes 4-bit input and activates one of the 15 matrix rows.
- Demux X: Built using 15 Demux Y modules, enabling selection of a specific column based on a second 4-bit input.
- X and Y Displays: Binary inputs are decoded and shown in decimal using combinational logic designed from truth tables and optimized using Karnaugh Maps.

- The project was built collaboratively, with weekly online meetings via Discord and WhatsApp.
- Tasks were divided, and constant testing ensured the project's success.
- Final validation was conducted by Professor Ramon Nepomuceno and teaching assistant Fagner, who approved the circuit's structure and functionality.
This project allowed for practical application of digital logic concepts and helped reinforce the understanding of:
- Data flow in digital systems
- Modular circuit design
- Simulation and debugging in Logisim ITA
- Technical documentation and teamwork
Cartesian Game stands as a complete and interactive digital circuit system, showcasing the potential of logic-based design.
