Thanks, i got the relays from "radio piet"
which is a local store in town.
Thanks for the link about port current.
I drawed what you say,
So that should be bassicly it, but where do i connect the wires to of the 2.7 volt circuit (2.7 if i remember correct, can be a bit more or less like 0.# ).
And this means that 5volt is coming out of all pins right?
Also a classmate of me buyed other relays a long time ago, he had 5 of them and 2 of them never worked he said. He went back to the local store and they measured it and they said they where ok. He's a noob just like me, but he was able to get the other 3 working, is this just luck?
