Hello,
What would be involved in adding a separate reset button to this project?

Thanks,
Ron

You mean an external one, e.g. on the side of a case? It's just a matter of wiring a switch (usually a pushbutton) between the Rst pin and ground.

If I have to use this kind of display https://www.digikey.com/en/products/detail/lite-on-inc/LTC-4624JR/408217 instead of the the 4 character display in the project what kind of hardware and software would I have to change?

You could probably wire it to the driver board if it's compatible, and use the existing library for the 4-digit displays. The driver and library would think it's a 4-digit display but only 3 of them would be real. So the only real change would be the hand wiring of the display. Just an educated guess, though. It really depends on how that display compares to the 4-digit ones Adafruit sells.
