start of timer project
I know basic electronics from years ago, and now want to design a timer that has several settings.
What I'm trying to design is a timer that has several settings for off time (say 1 day, 2 days, 4 days and 1 week), and a selectable on period (a couple of seconds to a few minutes).
What is the best way to get started? Should I be thinking with 555's ( but I don't think I can get the days of off time with these), or should I be thinking of using programmable chips?
I just need a bit of help to get started...
