[sdiy] sequential firing using Logic.

Check out the CD4017 chip "johnson counter with decoded outputs"

and also any multiplexer chips such as CD4051...

Basically you need to make a counter with decoded outputs.

It is also possible to make a 'ring counter' which passes
a pulse from stage to stage. These were common in the transistor
days... less common with ICs

Try Google for 4017, 4051, or "ring counter"
