Hi all! I’m struggling with controlling a 8 really panel. It seems to work backwards from what I’d expect…when the GPIO is “low” it turns relay on? I would have thought “high” would turn it on? Is there a method to get it to work this way?
Well…that was simple enough!
Just some more info for you, it depends on the type of relay you get. Some are active low and some are active high. From what you said you have an active low relay which can definitely get confusing. It should say in the specs what kind of relay it is.
