Complete LED newb here.
In this diagram, if the line from the PSU is 12V, what would I need to attach an LED to show that the circuit has been closed? I am guessing, from the comments I have heard here in passing, that I need some kind of resistor?
I can get this from Radio Shack? I would need about 10 of them.....
