Auto fade in and out.
I've got a (Vellerman) PWM device which is DC controlled. I'd like to use
it such that it fades up to max when a simple DC switch is made, then fades out when it is broken. I can get it to do this using a simple RC circuit - but the 'law' of the fades isn't as linear as I'd like. Any clever way of doing it? -- *Strip mining prevents forest fires.
