OpenSprinkler Forums Hardware Questions spark + relay = open sprinkler? Re: Re: spark + relay = open sprinkler?



Just to clarify, I am referring to the spark relay shield. I am curious if the two together might be enough to DIY without needing to solder (which I’m not great at). =)

I am sure some software changes would be necessary (which I am good at). I really want to be sure that the hardware included in the relay shield is sufficient to drive the open sprinkler system.
