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.
Some of these creatures give off light continually. Others flash their lights on and off by mixing their chemicals on queue or by covering their light organs with a flap of skin. The flashlight fish has a light-producing organ near its eyes that is covered with an eyelid-type flap. The fish can flash its light by opening and closing this flap.
