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.
1 LED Christmas lights, on the other hand, do not have bulbs (only covers) and generate very little heat. 2  For example, it takes only 4 watts to illuminate a 70-light LED string, but it takes 4-5 watts per bulb to illuminate a string of C7 incandescent lights.
