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.
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.…
32-bit microcontroller IP. The ARM company which designs the ARM cores doesn't make controllers itself, but licences the IP to other manufacturers. ARM is the leading 32-bit controller and is availabl…

A piece of measurement equipment which can visualize one or more signals simultaneously on a time scale.
Solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
Impedance defines the voltage/current characteristic of any dipole circuit.
a circuit that produces an output voltage that is proportional to the input voltage. One typical configuration consists of a pair of resistors in series from the input voltage to …
A digital signal that goes high and low at a specific frequency.

the assignment of numbers to objects or events. All measurements consist of three parts: magnitude, dimensions (units) and uncertainty.
Circuit to generate a signal a specific time after a trigger event. The timing can be defined by an RC time constant, or by clock pulses from an oscillator.
Questions regarding Li-ion batteries (Lithium-ion), including proper charging and usage.
A non-isolated DC-DC converter topology which outputs voltage less than or equal to the input voltage
Control refers to systems that control other systems, whether that be industrial machinery, lighting or devices used in a home
a property of a substance related to the amount of heat energy it contains.
Short for Liquid Crystal Display. LCDs consume little power, and exist in graphic LCDs, or segmented. The latter type is used for character and 7-segment digit display, and also in custom LCDs for con…
Electrical device that converts direct current (DC) to alternating current (AC).
A chip or a circuit that sends a signal with more current or voltage, or over longer distances.
Mains electricity, typically a higher voltage AC waveform used to deliver electrical power to households. In North America 120V, 60Hz, in most European countries 230V, 50Hz. What most people will pl…
Questions about the electrical implementation of Ethernet; ask another Stack Exchange for software or protocol questions. Specify the speed as 10/100BASE-T is somewhat different from 1000BASE-T, apart…

*Your* health and safety while working on electrical devices, and designing devices that will not shock, set fire to, or otherwise harm the user of the device.
a circuit that has two stable states and can be used to store state information.
the primary documentation about components, describing their functionality and electrical properties.
An optoelectronic device which combines an optical transmitter and receiver in a single package; commonly used in galvanic-isolated control applications such as power supplies.
an integrated circuit (chip) used in a variety of timer, pulse generation and oscillator applications. The part is still in widespread use, thanks to its ease of use, low price and…
Questions related to the design of circuits that supply or use a high voltage. There are a few definitions but the IEC definition of a high-voltage supply system is above 1000 Vrms AC or 1500 V DC.
How wires connect to terminals and to each other; coloring and organization schemes; appropriate wire selection and installation techniques
A mechanism for the control of program flow in a computer. When interrupted a computer saves it's present operational state and changes to execution of code that is dependent upon which interrupt was…
