Hi all,
I have been playing around with some 433Mhz remote control modules that are commonly available on eBay. So far I've had good luck with the kinds that use mini mechanical relays, like this one. There are three outputs for each relay: a common, normally open, and normally closed. Easy.
So now I have purchased this kind to play around with. Much smaller and I think it has solid state relays instead of mechanical relays. The problem I have is that I don't know how to connect to the relays. Each channel has only one pin, so not sure how to use this style. I tried using the ground for the common, but that didn't seem to work. I assume with only one pin it is normally open, but does anyone have any ideas what pin to use for the common? Of course the "instructions" are useless. I posted some photos of the module below.
Thanks!
Kevin
