I am trying to construct a simple device for turning on and off three lights (one at a time). I have a traffic light that was blown down during a recent hurricane (obtained from the road dept.). It's frame was too damaged to put back up, but the lights work great. I would like each light to come on for a period then go out and the next light come on. I was thinking of using a555 timer because several years ago I managed to construct a wavemaker device for my fishtank that alternates power to two pumps creating a nice water current. That device is still working like a champ today.
I looked at the plans for that wavemaker and I don't think it will do because I am trying to activate three items and not two. Can anyone suggest a solution? Thanks! Todd
