A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

DC stands for Direct Current, which means the flow of electric charge in a single direction. Examples of a DC source are batteries, solar panels, dynamos.
Please specify the battery type in your question. Include chemistry (e.g. lead-acid), voltage, number of cells and how they are connected (series or parallel), capacity (in A·h or W·h).
varying the duty cycle of a rectangle wave, usually with a constant frequency.
A switch-mode power supply (SMPS) switches been fully-on and fully-off states quickly to maintain voltage regulation. They offer lower power dissipation and run cooler than linear regulators that cont…
Refers to the conversion of electric power by using solid state components such as semiconductors. Can also generally apply to the field of electrical engineering which works with power electronics.
a 8- and 32-bit microcontroller core developed by Atmel. AVR was chosen as microcontroller for the popular Arduino SBCs.
A filter selectively processes input signals in frequency- or time-domain.
BJT stands for Bipolar Junction Transistor. It is a three-terminal electronic device constructed of doped semiconductor material and may be used in amplifying or switching applications.
A common actuator in robotics; it's usually made of a static magnet (stator) and a set of moving inductors, acting as electromagnets, connected to the circuit through brushes. Brushless motors use pha…
DC-DC conversion. Implies conversion of a DC voltage level up or down. DC-DC converter can be isolated or non-isolated. Electronically it can be done by many kinds of circuits, depending upon the appl…
a credit-card sized computer that plugs into your TV and a keyboard. There have been several generations of the device with improved performance, more memory, and more connectivity…
VHDL (VHSIC (Very High Speed Integrated Circuit) Hardware Description Language) is a hardware description language used in electronic design automation to describe and design digital systems such as f…
About issues caused by electrical noise, or improving the Signal/Noise ratio of an analog circuit.
Mechanical part providing electrical contacts for a cable or electronic circuit board.
Identify chips, connectors, cables, and other components, from photographs and descriptions of the surrounding circuitry or equipment.
a hardware description language (HDL) used to model electronic systems. It is most commonly used in the design, verification, and implementation of digital logic chips. Please also tag w…
a stream of information in the form of a varying quantity. Usually in electronics, signals can be in the form of voltages, currents, or radiated electromagnetic fields.
an imperative (procedural) systems implementation language. It was designed to be compiled using a relatively straightforward compiler, to provide low-level access to memory, to provide language …
Antenna (radio), also known as an aerial, a transducer designed to transmit or receive electromagnetic (e.g. TV or radio) waves. -Wikipedia
a multi-drop serial bus invented by Philips (now NXP) for communication between ICs on the same PCB, i.e. short distance.
a 2 terminal passive device that stores energy in a magnetic field.
A device or circuit that generates an AC signal at a certain frequency.
A measure of how much a conductor opposes current flowing through it. It can also refer to a part of a circuit, which has a non-negligible resistance value.
a low-level 3 or 4 wire serial bus interface with clock (SCLK), data in (MISO) and data out (MOSI). The fourth wire is a Slave Select to uniquely select a device on the bus. This signal is us…
a computer system designed to perform one or a few dedicated functions often with real-time computing constraints. It is embedded as part of a complete device often including har…
the metallurgic process used to fix electronic components to a PCB. Soldering can be done by hand or automatic. PTH boards were usually wave soldered, SMT uses reflow technology.
How many times something happens per second, measured in Hz (Hertz).
hooked up logically. If your question is about a specific schematic software package, use that tag instead.
A UART (Universal Asynchronous Receiver Transmitter) is a piece of logic that sends and receives data on a serial port.
the most basic elements in an electronic circuit. Characteristic is that they're in a single package. There are passive and active components, from as simple as a zero -ohm resistor to …
transmitted as a sequence in time. Main advantage: much less wires needed. Main disadvantage: Higher bandwidth for the same throughput.
The kind of magic without which all of this wouldn't be possible. This tag should be used for questions about the **physics** of the fields that charged particles create and how these fields interact.…
the reference point in an electrical circuit from which other voltages are measured, or is a common return path for electric current, or a direct physical connection to the Earth.
