Is there a more specific term for "driver"? I am not familiar with a
component by that name.

A flip-flop basically stores a 1 or a 0, ON or OFF, respectively. It can't
switch between the two by itself. It needs additional circuitry to drive
it,
or basically tell it when to switch the flip-flop from 0 to 1, and 1 to 0.

what are the characteristics of the signal required to cause the bit to
change?

A PIC would suit perfectly for this type of application but it requires
some
funds for a PIC programmer (hardware) and coding the PIC (software). You'd
have to know how to program to use a PIC.

Does PIC stand for Programmable IC? Is this similar to an EPROM or PROM?
How much does PIC programmer hardware cost?

What skills are necessary for programming to use a PIC? For example, if one
is versed in machine language, is that sufficient?

Thanks for the information. It sounds intriguing.
