This week we had our demo days to showcase what we have created so far. In terms of design, our current system is bare bones and not cohesive, but the core functionality of all the parts have been implemented. On the hardware side, the capacitive touch sensor is working, and the numpad and projector can communicate with our software. However, we do need to continue integrating additional features onto our software. Our hint system is not where we want it to be at the moment, as it only gives the user the answer to a specific cell.
Since last week, I spent more time on the hardware-software integration and finally got the capacitive touch sensor to communicate with the Raspberry Pi through Pygame. Now we no longer need the mouse and keyboard to interact with our Sudoku board. The capacitive touch sensor is used to select a cell and the numpad is used to enter numbers, delete numbers, and ask for a hint. I can now focus fully on just the software, and I’ve begun writing some code to have a multi-functional side screen next to the Sudoku board that we will use for displaying a home screen and options.
