I am trying to design a circuit that will send power to a series of points in order (for example, first circuit a is powered, then circuit b, then c, etc.) The only way I can think to do this is to use a 555 timer to create a triangle wave and a voltage divider connected to a series of op-amps, but this seems rather complicated and I was wondering if there was a simpler way to accomplish this. Thanks.

For this purpose, 4017 ic is your friend. See **broken link removed**.
