I am currently working on some improvements on my motorbike, and one of them requires something I have never done before.
I am adding 2 12v LED strips (well, they're built in a piece I am mounting, but that doesn't change anything for the electronics), with the idea that they will normally go on when I power the motorbike and serve as DRL. But I want them to also blink as warning lights when I turn on a switch when I am lane splitting. This of course means that when they blink, the continuous power should be turned off.
So the idea is to make 2 circuits with the same LED strips, one that simply runs the power through it, the other one with a blinking relay in line, and have a relay make the switch from the one to the other. Now I have never worked with a relay before. I think I grasp the concept, there is one circuit (NC) that is closed when the relay is not powered (that would be my DRL circuit) and one circuit (NO) that will close when the relay is powered. As I understand, the COM is basically the power "input" that wil be directed either towards NC or towards NO depending on the state of the relay. The DC+ and DC- seem rather transparent as well although I don't know how things would work inside the relay.
Now the big question: is the IN the key contact that will determine whether the relay is powered or not?
