Hi,

What would be the simplest circuit to control the frequency
and
brightness of an LED (100Hz maximum at 1watt max power) with
microcontroller control.

The *simplest* circuit hardly requires a microcontroller !

Nonsense! Perhaps you'd better read the requirements statement
again; "with microcontroller control".

Which is why I phrased my answer as I did.

Geez Pooh, I thought you were a businessman. He asked for a
solution
*specifically* using a microcontroller and here you are telling him
that
it's the wrong solution.

I have often found that ppl are chasing the wrong solution, usually
on the
basis of bad advice or incorrect assumptions.

Perhaps it's you who have the incorrect assumptions?

Perhaps he already has one in the design?
Sometimes a microcontroller *is* the right answer (particularly
when the
customer asks for one).

The OP asked for simple.

UCs *are* simple. Transistors are free. It's the packaging that
cost$. ;-)

Quite often ppl get 'wrapped up in technology' for the sake of it
and simple
becomes not so simple. If we knew *why* he wanted a uC maybe it
would make
more sense ?

It makes sense because that's what he asked for. Maybe you want to
ask
for the whole problem, rather than assume a UC is the wrong solution?

Here here! I get the idea that Pooh doesn't "dig" micros, period.

You'd be very mistaken.

I have actually designed in micros where they once would have seemed an
unusual choice.

It's a question of the right tool for the job.

Unless the strobe led needs to be remote controlled, I see no reason for a
uC.
