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.
As the trend took off, it became apparent that lighting up the Christmas tree and house definitely took effort and money. For many people, the only Christmas light display option was to light up the tree with candles, because they could not afford to buy lights. The trees would be displayed for only a couple of days before Christmas, and the candles were only lit for a few minutes at night, a far cry from the elaborate tree and home displays we are familiar with today.
