hmm right, i have made my first PWM (yay ) but i want to expand it further - however, I do not want to use picaxe's since the programming board is around £40 and I dont want to spend that
So here is the PWM - what I want it to do is sweep from a low duty cycle (since i noticed that it doesn't actually go fully off, but very dim) to maximum, hold it there for a second or two and then come back and hold.
Any ideas? Do digital potentiometers exsist?

Oh and please don't take me back to LEDs, 555s, Flashers, and Light Chasers - I've read it enough times
thanks
