Pro/Forums - View Single Post - Electronics experts, looking for a schematic...

Okay I found something a little helpful HERE. About halfway down the page there is a schematic that uses a 555 timer to make the LED display count from 0 to 9 or 9 to 0. Now I just need to figure out how to replace the timer part with something that would react to a voltage change.

I'll keep looking. Maybe someone can offer a suggestion.

Thanks
