timer control
(OP)
Hey there: I need to control 4-6 on functions per day for a on time of 5-30 seconds per event. I am a mechanical guy so out of my depth with the wires. The system is 12 volt for a greenhouse irrigation system. Thanks!

I don't see why you can't just use a standard sprinkler timer, which does the start and cycle times, and with some minor circuit mods, could handle more than 3 events per timer:

Or for something easier to program, but more expensive:

You can program the relays to pulse on and off, etc over the serial interface. Also has IR control as well.
