My son recently discovered Sudoku and I recently discovered MicroView. So, I decided to make a Sudoku puzzle solver using the little screen.

I wanted the MicroView screen to show a real-time view of the puzzle as it is being solved. No font was small enough, though! I needed a reasonably legible number font that could fit 9 digits vertically. I was able to make a 2x4 font that did the job (but there’s no zero (looks like an equals sign) and the 8 and 3 are a little obscure). For Sudoku, this worked great!

Let me know what you think!

You can also use symbols instead of numbers - works the same

Cool project
