greetings,
I hope you all can help. I stumbled across your forum while searching for the solution to a project that I've been put in charge of. It involves finding a way to control a multi light LED position indicator. (red/yellow/green) The best way to detect our device's position is with a pull string potentiometer.
(see http://www.celesco.com/_datasheets/sp1.pdf ) I need a circuit that will light up more lights as the position of the potentiometer changes. If that's not tricky enough, I would need to be able to adjust where in the stroke the high and low lights come on. It would only be activated by the push of a button (that part of the circuitry I can handle) and will need to run on a 9v battery. I've searched your projects and experiments but haven't found quite what I need. Any advise, schematics, links and suggestions would be greatfully considered.
Thank you in advance for your time and consideration.
