Why use software PWM when that chip has it in hardware? Trivial to set
up and control with a pot. I reckon you could buy the chip and a capable
transistor cheaper than the equivalent non micro components needed to do
PWM.


Oh yeah... so it has! I should have checked the spec sheet first,
shouldn't I? :-)

I might have a go at building this just for fun!
