PeterH:

creativen:
this kind of led I refer to, but it is with different relay

I don't understand what that means. Is there a second LED involved, somehow?

What I mean is: that kind of schematic I do for my grove test, but not with that kind of relay.
I use the relay from here: http://www.seeedstudio.com/wiki/GROVE_-_Starter_Kit_V1.0b
