I am trying to design a one time programmable lawn sprinkler controller to trigger on/off 24V 750ma lawn sprinkler valves. A set and forget sprinkler timer that once the time/date are set, it does the rest.
The project needs to allow for programming on/off time for 7 days per week during summer months and switch to a "winter" program during fall/winter months. Once the timer program is set, it will never change for the life of the sprinkler system (so I need a calendar of 10-20 years).
Any ideas on what ICs to start with to get the calendar, 24 hour timer, and triggers?
Has anyone done this already and willing to share circuit design?
Thanks
