Electronic diagrams are like descriptions of electronic circuits. They show you which materials to use and how to mix them. However, instead of using text to describe the recipe, a drawing is used. These are also called circuit diagrams.
For what purpose
This is a method that explains how you can achieve a particular result. When you want to do something in electronics, creating a schematic diagram shows you the roadmap of the circuit to be created. If there are any errors later on this diagram can be checked easily.
A schematic diagram shows which components and which components are connected.
It consists of electronic symbols representing each of the components used. The symbols are interconnected by lines showing how the components are connected. Each of the lines shows the wires. They show how the components are connected. If you want to create the circuit, you only need to identify the components and then connect them as shown in the circuit diagram. This can be done with a bulletin board, a ribbon, or you can design your own printed circuit board (PCB) if you wish. When you have schematics, you don’t really need to know any electronic theory. But having basic electronic knowledge can help you.
What are the circuit types?
Although it may vary according to the needs, it can be classified as simple (electronic) circuits, power supply diagrams, motor related circuit diagrams, sensors connected diagrams, audio circuit diagrams, digital circuits.
