This is so cool, especially for those of us who've used rotary phones.

I'd like to see a video of a google voice or other call made using the rotary number pad :)

We had a rotary phone when I was young.

What would be really cool is to see some version of “Minority Report” actually work in my lifetime.

Sort of like people who lived during the invention of the airplane and got to see humans land on the moon

> While one could use a pin-change interrupt, the timescale is so large that busy-waiting is acceptable.

You should never use interrupts for this sort of input with lots of inherent switching noise. At best you could wait for one interrupt then disable it while polling in a debounce routine. Interrupts are a red flag that someone hasn't investigated what the switching is doing to their micro.
