Hello
I want to make a circuit that flashes four LEDs (or reed relays) in a pseudo-random sequence, with each flash lasting about half a second. It's important that only one LED is on a time, and I want it to be automatic (eg not triggered by pushing a switch). I feel that this ought to be fairly easy but I don't quite see how to do it and don't want to reinvent the wheel. Help appreciated, thanks
