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.
There are several ways of making a blinking LED circuit. You can make one using relays. Or you can make one using transistors. Or you can make one using components like a 555 Timer or a microcontroller. Letâs look at one circuit using relays and one using transistors.he easiest way to get a light to blink (or at least the easiest to understand) is the following: In the above circuit you see a battery, a relay (in the red square) and a light bulb. To understand the circuit you need to understand how a relay works.
