So, I have finished my WC8 12 chicken temperature project - chickens still alive, nothing burned down and all low voltage of course.
Now that the ElectricBug has bitten, would like to move on to controlling main electric 110V gadgets, such as lights, 110v, 50W aquarium heaters, 20W aquarium pumps.
having read a ton on relays, mostly from sigehts such as Ardunio, it makes it all sound somewhat simple: run the black wire of your electrical component through the ground and AlwaysOpen or AC portion of relay, apply 24V tot he relay board (mine is a 24v) and plug in power last (I am putting this here to prevent the ' make sure you don't cu wires while plugged in responses, although I am sure I will not think of something that should have been logical).
The board I purchased for trial and error is: amazon.com/dp/B00GGKLFX0/ref=pe_385040_30332190_TE_3p_dp_1 a generaic 8CH relay board using SRD-24VDC-SI,C relays by ? songle ?
My question: Is there nothing else needed, no diodes no nothing?
