I was taking an electronics course, way back in high school. Which was quite a while ago.
I remember playing with a component that let me light up an LED. It wasn't really complicated. But it seemed to be just a small piece of metal (or something metallic), connected to wires. All I had to do was light a match and it place it below the metal part, which then lit up the LED. So it was some sort of thermal/radiation absorbing component.
Does anyone know the technical name for this component?
