Relationship to electrical engineering[edit] Electronics is a subfield within the wider electrical engineering academic subject. An academic degree with a major in electronics engineering can be acquired from some universities, while other universities use electrical engineering as the subject. The term electrical engineer is still used in the academic world to include electronic engineers.
In the old days there was a gizmo that plugged into an outlet that you then plugged your light set into that made the set blink on & off. It's so simple that it isn't made anymore. All I want to do is make an LED light set blink on & off. I don't want computer control.
Why do you need load resistors? Resistors prevent the LED turn signal bulbs from hyper flashing. Here is a video comparing the same LED turn signal light bulb without the load resistor. It blinks faster than normal. After you tap it with the load resistor, the LED bulbs will blink at the normal speed (about 0.8-1.0 second per blink)
