One of my little copy/paste projects died again (a 12V 1 A circuit - last time it died). Now it was a short that caused it.
Is there a simple way of keeping my parts from burning? By simple I mean something like a resistor that will burn before more expensive parts will, and that will cause the circuit to stop receiving power.
Also what are the problems that come with being simplistic?
Edit 1: So the circuit after all the answers looks like this:
