Remember, the Arduino is not the board, but the IDE and libraries behind
it. There are a ton of chips you can use as a Arduino, from a Attiny45
up to a Atmega1280 and even a esp8266 wifi module. and with the latest
Arduino IDE'sthere is a system to add "cores" for other processor
architecture like ARM or intel.
as a bare minimum, you need a chip like the atiny45. not even a
oscillator or pull up resistors are needed. but then of course you need
a programmer to get the code onto your chip, like the avrispmkII or
similar. those can aslo be used from within the IDE by pressing shift
while clicking upload. and a bootloader (if needed) can also be put on
the chip with the programmer. then serial uploading works.

I'm thinking that, to finalize this mod, I'll need to make my own little PCB. I then though, hey, if I'm going to make a custom PCB, why not build the Arduino right into the board!?! I don't know how to do that, but I figured that I'd give it a try.

Oh, the fun that could be had!
