Understanding how to read and follow schematics is an important skill for any electronics engineer. This tutorial should turn you into ...See full list on learn.sparkfun.comSchematic comprehension is a pretty basic electronics skill, but there are a few things you should know before you read this tutorial. Check out these tutorials, if they sound like gaps in your growing brain: What is Electricity? What is a Circuit? Voltage, Current, Resistance, and Ohm's LawSee full list on learn.sparkfun.comAre you ready for a barrage of circuit components? Here are some of the standardized, basic schematic symbols for various components.See full list on learn.sparkfun.comThe most fundamental of circuit components and symbols! Resistors on a schematic are usually represented by a few zig-zag lines, with two terminals extending outward. Schematics using international symbols may instead use a featureless rectangle, instead of the squiggles.See full list on learn.sparkfun.comVariable resistors and potentiometers each augment the standard resistor symbol with an arrow. The variable resistor remains a two-terminal device, so the arrow is just laid diagonally across the middle. A potentiometer is a three-terminal device, so the arrow becomes the third terminal (the wiper).See full list on learn.sparkfun.comThere are two commonly used capacitor symbols. One symbol represents a polarized (usually electrolytic or tantalum) capacitor, and the other is for non-polarized caps. In each case there are two terminals, running perpendicularly into plates. The symbol with one curved plate indicates that the capacitor is polarized. The curved plate usually repres...See full list on learn.sparkfun.comInductors are usually represented by either a series of curved bumps, or loopy coils. International symbols may just define an inductor as a filled-in rectangle.See full list on learn.sparkfun.comSwitches exist in many different forms. The most basic switch, a single-pole/single-throw (SPST), is two terminals with a half-connected line representing the actuator (the part that connects the terminals together). Switches with more than one throw, like the SPDT and SP3T below, add more landing spots for the the actuator. Switches with multiple ...See full list on learn.sparkfun.comJust as there are many options out there for powering your project, there are a wide variety of power source circuit symbols to help specify the power source.See full list on learn.sparkfun.comMost of the time when working with electronics, you'll be using constant voltage sources. We can use either of these two symbols to define whether the source is supplying direct current (DC) or alternating current (AC):See full list on learn.sparkfun.comBatteries, whether they're those cylindrical, alkaline AA's or rechargeable lithium-polymers, usually look like a pair of disproportionate, parallel lines: 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 ...See full list on learn.sparkfun.comBasic diodes are usually represented with a triangle pressed up against a line. Diodes are also polarized, so each of the two terminals require distinguishing identifiers. The positive, anode is the terminal running into the flat edge of the triangle. The negative, cathode extends out of the line in the symbol (think of it as a - sign). There are a...See full list on learn.sparkfun.comTransistors, whether they're BJTs or MOSFETs, can exist in two configurations: positively doped, or negatively doped. So for each of these types of transistor, there are at least two ways to draw it.See full list on learn.sparkfun.comBJTs are three-terminal devices; they have a collector (C), emitter (E), and a base (B). There are two types of BJTs -- NPNs and PNPs -- and each has its own unique symbol. 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 ...See full list on learn.sparkfun.comLike 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: The arrow in the middle of the symbol (called...See full list on learn.sparkfun.comOur standard logic functions -- AND, OR, NOT, and XOR -- all have unique schematic symbols: Adding a bubble to the output negates the function, creating NANDs, NORs, and XNORs: They may have more than two inputs, but the shapes should remain the same (well, maybe a bit bigger), and there should still only be one output.See full list on learn.sparkfun.comSome 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. Often, there will be two op amps built into one IC package requiring only one pin for power and one for ground,...See full list on learn.sparkfun.comCrystals or resonators are usually a critical part of microcontroller circuits. They help provide a clock signal. Crystal symbols usually have two terminals, while resonators, which add two capacitors to the crystal, usually have three terminals.See full list on learn.sparkfun.comWhether it's for providing power, or sending out information, connectors are a requirement on most circuits. These symbols vary depending on what the connector looks like, here's a sampling:See full list on learn.sparkfun.comWe'll lump these together, since they (mostly) all make use of coils in some way. Transformers (not the more-than-meets-the-eye kind) usually involve two coils, butted up against each other, with a couple lines separating them: Relays usually pair a coil with a switch: Speakers and buzzers usually take a form similar to their real-life counterparts...See full list on learn.sparkfun.comFuses and PTCs -- devices which are generally used to limit large inrushes of current -- each have their own unique symbol: 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 abov...See full list on learn.sparkfun.comOne 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.See full list on learn.sparkfun.comValues 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 ...See full list on learn.sparkfun.comComponent 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 R1,...See full list on learn.sparkfun.comUnderstanding which components are which on a schematic is more than half the battle towards comprehending it. Now all that remains is identifying how all of the symbols are connected together.See full list on learn.sparkfun.comSchematic nets tell you how components are wired together in a circuit. Nets are represented as lines between component terminals.
