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.
electromagnetism× 834
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.…
arm× 831
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…
oscilloscope× 806
A piece of measurement equipment which can visualize one or more signals simultaneously on a time scale.
solar-cell× 797
Solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
voltage-divider× 751
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 …
ltspice× 734
a SPICE simulation, schematic capture and waveform viewer program from Linear Technology. LTspice is freeware with very liberal license, it is lightweight and i…
measurement× 705
the assignment of numbers to objects or events. All measurements consist of three parts: magnitude, dimensions (units) and uncertainty.
timer× 701
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.
lithium-ion× 681
Questions regarding Li-ion batteries (Lithium-ion), including proper charging and usage.
buck× 675
A non-isolated DC-DC converter topology which outputs voltage less than or equal to the input voltage
control× 674
Control refers to systems that control other systems, whether that be industrial machinery, lighting or devices used in a home
lcd× 658
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…
driver× 656
A chip or a circuit that sends a signal with more current or voltage, or over longer distances.
mains× 656
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…
ethernet× 651
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…
safety× 648
*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.
datasheet× 641
the primary documentation about components, describing their functionality and electrical properties.
opto-isolator× 623
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.
555× 609
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…
high-voltage× 605
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.
wiring× 602
How wires connect to terminals and to each other; coloring and organization schemes; appropriate wire selection and installation techniques
interrupts× 585
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…
