Electric Circuits and Gadgets -- Basics Please Well, when I lived in India, I remembered a neighbor whose occupation was creating little gadgets, such as watches, lasers, etc. I am now living in Pakistan, and missed the chance of asking the guy how he learned what he knew. I am curious to just basically learn what are the functions of basic hardware components that creates such hardware. Can anyone give me a runway of this field, and give me a sense of how different components come together to operate a gadget? I apologize if my English is not good, but it is not my first language and I am only 14 years old.
