More pairs of lines usually indicates more series cells in the battery. Also, the longer line is usually used to represent the positive terminal, while the shorter line connects to the negative terminal. Voltage NodesSometimes - on really busy schematics especially - you can assign special symbols to node voltages. You can connect devices to these one-terminal symbols, and it'll be tied directly to 5V, 3.3V, VCC, or GND (ground). Positive voltage nodes are usually indicated by an arrow pointing up, while ground nodes usually involve one to three flat lines (or sometimes a down-pointing arrow or triangle). The collector (C) and emitter (E) pins are both in-line with each other, but the emitter should always have an arrow on it.
If the arrow is pointing inward, it's a PNP, and, if the arrow is pointing outward, it's an NPN. A mnemonic for remembering which is which is 'NPN: not pointing i n.' Metal Oxide Field-Effect Transistors (MOSFETs)Like BJTs, MOSFETs have three terminals, but this time they're named source (S), drain (D), and gate (G).
And again, there are two different versions of the symbol, depending on whether you've got an n-channel or p-channel MOSFET. There are a number of commonly used symbols for each of the MOSFET types.
Schematic symbols for an ATmega328 microcontroller (commonly found on ), an ATSHA204 encryption IC, and an ATtiny45 MCU. As you can see, these components greatly vary in size and pin-counts.Because ICs have such a generic circuit symbol, the names, values and labels become very important. Each IC should have a value precisely identifying the name of the chip. Unique ICs: Op Amps, Voltage RegulatorsSome of the more common integrated circuits do get a unique circuit symbol.
You'll usually see operation amplifiers laid out like below, with 5 total terminals: a non-inverting input (+), inverting input (-), output, and two power inputs. The PTC symbol is actually the generic symbol for a thermistor, a temperature-dependent resistor (notice the international resistor symbol in there?).No doubt, there are many circuit symbols left off this list, but those above should have you 90% literate in schematic reading. In general, symbols should share a fair amount in common with the real-life components they model. In addition to the symbol, each component on a schematic should have a unique name and value, which further helps to identify it. Name Designators and ValuesOne of the biggest keys to being schematic-literate is being able to recognize which components are which. The component symbols tell half the story, but each symbol should be paired with both a name and value to complete it.
Names and ValuesValues help define exactly what a component is. For schematic components like resistors, capacitors, and inductors the value tells us how many ohms, farads, or henries they have. For other components, like integrated circuits, the value may just be the name of the chip. Crystals might list their oscillating frequency as their value. Basically, the value of a schematic component calls out its most important characteristic.Component names are usually a combination of one or two letters and a number.
The letter part of the name identifies the type of component - R's for resistors, C's for capacitors, U's for integrated circuits, etc. Each component name on a schematic should be unique; if you have multiple resistors in a circuit, for example, they should be named R 1, R 2, R 3, etc. Component names help us reference specific points in schematics.The prefixes of names are pretty well standardized. For some components, like resistors, the prefix is just the first letter of the component. Other name prefixes are not so literal; inductors, for example, are L's (because current has already taken I but it starts with a C.electronics is a silly place).
Here's a quick table of common components and their name prefixes:Name IdentifierComponentRResistorsCCapacitorsLInductorsSSwitchesDDiodesQTransistorsUIntegrated CircuitsYCrystals and OscillatorsAlthough theses are the 'standardized' names for component symbols, they're not universally followed. You might see integrated circuits prefixed with IC instead of U, for example, or crystals labeled as XTAL's instead of Y's. Use your best judgment in diagnosing which part is which. The symbol should usually convey enough information. Each net with the same name is connected, as in this for an. Names and labels help keep schematics from getting too chaotic (imagine if all those nets were actually connected with wires).Nets are usually given a name that specifically states the purpose of signals on that wire. For example, power nets might be labeled 'VCC' or '5V', while nets might be labeled 'RX' or 'TX'.
Schematic Reading Tips Identify BlocksTruly expansive schematics should be split into functional blocks. There might be a section for power input and voltage regulation, or a microcontroller section, or a section devoted to connectors.
Try recognizing which sections are which, and following the flow of circuit from input to output. Really good schematic designers might even lay the circuit out like a book, inputs on the left side, outputs on the right. Like-named voltage nodes - like GND, 5V, and 3.3V - are all connected to their counterparts, even if there aren't wires between them.The ground voltage node is especially useful, because so many components need a connection to ground.
Reference Component DatasheetsIf there's something on a schematic that just doesn't make sense, try finding a datasheet for the most important component. Usually the component doing the most work on a circuit is an integrated circuit, like a microcontroller or sensor. These are usually the largest component, oft-located at the center of the schematic. Resources and Going FurtherThat's all there is to schematic reading!
Knowing component symbols, following nets, and identifying common labels. Understanding how a schematic works opens up the whole world of electronics to you! Check out some of these tutorial, to practice your new-found schematic knowledge:. This is one of the most basic, fundamental circuits.
Learn how to turn a big voltage into a smaller one, with just two resistors!. Now that you know how to read schematics, why not make one!
Breadboards are a great way to make temporary, functional, prototype circuits. Or, skip the breadboard and jump straight into wiring stuff up. Knowing how to cut, strip, and connect wire is an important electronics skill. Building circuits in series or parallel requires a good understanding of schematics. If you don't want to work with wire, how about building an e-textiles circuit with conductive thread? That's the beauty of schematics, the same schematic circuit can be built in a number of different ways with a number of different mediums.
