Our team has made significant progress on our Sudoku project, focusing on integrating hardware and software components for a functional minimum viable product. The software development has advanced well, with successful integration of the Raspberry Pi and Sudoku board software, including numpad input functionality and code modularization for more efficient row and column readings.
On the hardware side, we built a 9×9 grid using wood, copper foil tape, and cardstock, and successfully connected both MPR121 sensors. However, we encountered a challenge with the cardstock, causing inconsistent sensitivity in the capacitive touch sensors. As a temporary solution, we’re keeping both grid components separate while designing a new enclosure with acrylic sheets and considering 3D printed clamps for better material stability.
Our testing of the system has successfully projected the Pygame display and adjusted visibility and alignment using a stand. While most software components are ready for demonstration, we’re still working on consistent operation of the capacitive touch sensors to replace mouse input with touch selection. We plan to meet another time before demo day to finalize the touch sensor integration and prepare for the demo.
