The Arduino program needed some tweaking. The Raspberry Pi had trouble keeping up with the rapid-fire inputs from the emulated keyboard, and a misstep could turn into an unwanted command. Unexpected commands would grow because a cell with surprise data might mess up one of the reliable cells, then there is a bunch of number-salad on the screen.

To add robustness, I retype the critical equation each time, so when it gets erased by accident, it gets healed. Another problem was erasing working cells, so I added some space between the enunciated line and the rest.
