SCHOOL PHYSICS PROJECT
i made a cool thing for my computer, seen here: http://www.bandtank.com/stuff/movies/MVI_1646.AVI
its just a 555 timer that is speed controlled by a 100k pot (i think i got the diagram from this forum!)
i was wonder how to make this into something that would make the LEDs "run" back and forth instead of blink 4 at a time.
can anyone give me any input on this?
i got a reply about using a decade counter... not sure how to do this though. I have an NTE74192 right here if its possible to use that...
any input would be great!
thanks
david
