Reading a circuit schematic requires a solid understanding of various concepts and components. Heres a comprehensive guide to the knowledge required.
Basic 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.com Transistors, 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.com Our standard logic functions -- AND, OR, NOT, and XOR -- all have unique schematic symbols: Adding a bubble to the output negatesthe 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.com Integrated circuitsaccomplish such unique tasks, and are so numerous, that they don't really get a unique circuit symbol. Usually, an integrated circuit is represented by a rectangle, with pins extending out of the sides. Each pin should be labeled with both a number, and a function. Because ICs have such a generic circuit symbol, the names, values... See full list on learn.sparkfun.com Crystals and Resonators Crystals 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. Headers and Connectors Whether 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: Motors, Transformers, Speakers, and Relays We'll lump these together, since they (mostly) all make use of coils in some way. Transformers (not the more-than-meets-the-eyekind) usually involve two coils, butted up against each other, with a couple lines separating them: Relaysusually pair a coil with a switch: Speakers and buzzersusually take a form similar to their real-life counterparts: And motorsgenerally involve an encircled "M", sometimes with a bit more embellishment around the terminals: See full list on learn.sparkfun.com View all A beginner's guide to reading and understanding schematic diagrams, complete with descriptions and images of each schematic symbol.
