A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension. For example, a subway map intended for riders may represent a subway station with a dot; the dot doesn't resemble the actual station at all but gives the viewer information without unnecessary visual clutter. A schematic diagram of a chemical process uses symbols to represent the vessels, piping, valves, pumps, and other equipment of the system, emphasizing their interconnection paths and suppressing physical details. In an electronic circuit diagram, the layout of the symbols may not resemble the layout in the circuit. In the schematic diagram, the symbolic elements are arranged to be more easily interpreted by the viewer.
Schematics and other types of diagrams, e.g.,
How to read a schematic, follow electronics circuit drawings to make actual circuits from them. This starts with the schematic for a very simple circuit with just some batteries, resistor, switch and an LED. Then it talks about Earth ground and chassis ground. Finally it moves on to a crystal radio amplifier schematic and adds a diode, potentiometer and capacitors.

With so many designs available on the web, understanding how to read schematics can unlock a world of possibilities for the electronics maker. In fact, if you can read a schematic, you can build a circuit before even understanding how it works!
Here are a few of the most common symbols that you'll encounter in schematic circuit diagrams.
Reading schematics isn't that hard when you know what all the symbols mean.

Basic principles of reading a simple schematic and building a circuit on breadboard. For beginners
Well I've been pacing up and down your drive.
Trying to get the nerve affirm that I'm the only one
Who you should give of your affection.
But you were watching me from your window.
Your bag was packed and your were rearing to go along with me.
And on this ride all my attention you've got.
Oooo.
I could tell by the way you were looking at me I was found.
You counted down you watched my every move.
Like a blindman finally seeing something.
I've been finding every road has led to you.
But hey all I've ever wanted is to play hide and seek
Oh for two.
Well under the setting sun we started off and played this game.
You are it and I'm on the run.
I know I'll never be the same again.
Well everything I've ever dreamed of you've got.
Oooo.
I could tell by the way you were looking for me I was found.
For you counted down you knew my every move.
Like a wiseman holding all the answers.
I've been swimming in a crowded pool of fools.
Hey but all I've ever wanted...
Oh you say you'll take me just the way I am.
Without the welcome mat and I want you yeah.
Light the candles and we'll start again.
I'm going to count to ten then come find you.
You know I've gotta find you.
Oooo.
Can you tell by the way I'm looking at you this is real?
Well this is how I feel.
I'm falling into you.
Like an agoraphobiac's gotta dive in.
I jumped out and I left my parachute.
You see all I've ever wanted is to play hide and seek
With only you.
