Having a little information overload in addition to being extremely green at this.
Purchased the WebController in order to automate some Chicken Coop/Run projects, such as automated door opener, turning on/ off fans,e tc
I do now understand that I should have a relay which allow control of higher voltaged (24V or 110V) equipment. Actually and initially thought I would be using DtDP relays, but, with all the reading it seems better to use relay boards. Here the problem: which board?
I see in many threads that AZctive High is the way to go, but almost everything seems to be active Low -
This board -SainSmart 4-Channel Relay Module - was mentioned as good by someone, but reading the details on the board seems that is also Active high? Or, I am not understanding the concept yet.
Any help would be appreciated,
Rainer
