Microcontroller is an electronics word ,the very name of which puts off oldtimers of electronics hobbyists thinking that it is a very high tech item and they would not be able to understand much.Knowledgeable people in this area deliberately make it so with high sounding words like Atmel 8051, PIC, Arduino, Raspberry Pi with still scaring words like assembly/C/C++ programming,data structure, Python,compiler , execution etc.These are actually misnomer and as simple as switching on/off a lamp which any school child can understand with proper guidance. To start with let me first deal with so called 8051 microcontroller in the simplest possible way. Pls watch the video link .

Optocouplers for AC & DC
Optocouplers are used mostly in power electronics circuits to isolate the fatal mains utility voltage to that of the low dc voltage that the control circuit works. Therefore some call it optoisolators. They find use in control circuits feeding Thyristors,MOSFETs,IGBTs. Submitted below an audio visual for better understanding.
