I have decided to used inclinometers and linear actuators as my input and output devices. I have built one circuit which uses comparators to determine the direction of the drive to the actuators and PWM (using a 555 timer) to vary the speed around the level position. My problem is the PWM circuit requires potentiometers to vary the Mark to space ratio. I was wondering if there is a any way to vary the speed using PWM by the changing voltage input from my Inclinometers. The inclinometers produce a signal ranging from 0V to 12V. Ideally I would like a high mark space ratio at both 0 and 12V getting lesser as it tends to 6V (the equalibrium position as it were.) Any help would be gratefully appreciated. So too would be relevant web sites or literature. Thanks Andrew Douglas
