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.

A kind of motor that moves in steps.
Switching can be defined as the change in state whether it be an analog, digital, or mechanical device. For digital devices, switching can be defined as a transition from HIGH to LOW or vice versa. Fo…
Electromagnetic compatibility (EMC) is a branch of electronics related to identifying and solving problems caused by electromagnetic interference (EMI) between devices. It encompasses both attempting …
The ESP8266 is a low-cost Wi-Fi chip/module with UART connections and a built-in TCP/IP stack. It has an Xtensa single-core 32-bit L106 MCU, usually running at 80 MHz.
For questions about the ESP32 series of microcontrollers. Use in conjunction with the "microcontroller" tag.

Differential refers to any kind of signaling where the signal information is carried by two or more paths and both are required to properly reconstruct the signal. For example, USB D+ and D-
A device which controls the voltage and current being delivered to a capacitor or battery.
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…
Capacitance is the ability of a body to store an electrical charge.
These are part of AC to DC conversion. A half-wave rectifier keeps only the positive part of the signal. A full-wave rectifier also keeps the negative part, but flips it to make it positive too.

An electronic component that sources current - if it sinks current it is called a current sink but both devices (sinks and sources) can be called sources. An IDEAL current source will supply current, …
Ancillary circuitry that protects the main circuitry in case of a fault. Examples of faults protected against are: overvoltage, ESD, overheating, and overloading (too high of a current draw). In some …
An LED driver is a self-contained power supply that controls the amount of current and voltage supplied to an LED light. An LED constant current driver monitors the loop current of each LED and automa…
