What I wanted to say no 555 and mo micro alone can do anything.
There where other parts to add some functionality. It depends on energy at
least to do something. It isn't relevat if there is a 555 or a micro, alone
they make pretty little bugs that sit on the table...

There is no Application jou can just build out of
a 555 nor there is
one that only uses a micro. So what?
Is that true? I routinely use an 8-pin PIC to develop a READY/
signal from the INDEX/ signal on a floppy drive. Other than +5 for
power supply, it requires no components. I could have done the same
thing with a 555 or two, but I'd have to add R and C to make it work.
That same PIC could potentially serve as a timer with a period in
centuries without any external components--something an 555 could not
do.
