    en.wikipedia.org/wiki/General-purpose_input/output

    A general-purpose input/output (GPIO) is an uncommitted digital signal pin on an integrated circuit or electronic circuit (e.g. MCUs / MPUs) board which may be used as an input or output, or both, and is controllable by software. GPIOs have no predefined purpose and are unused by default. [1][2] If used, the purpose and behavior of a GPIO is ...

    en.wikipedia.org/wiki/Physics-informed_neural...

    Physics-informed neural networks for solving Navier–Stokes equations. Physics-informed neural networks (PINNs), [1] also referred to as Theory-Trained Neural Networks (TTNs), [2] are a type of universal function approximators that can embed the knowledge of any physical laws that govern a given data-set in the learning process, and can be described by partial differential equations (PDEs).

    ATtiny microcontroller comparison chart. ATtiny2313 in 20-pin narrow dual in-line package (DIP -20N) ATtiny (also known as TinyAVR) is a subfamily of the popular 8-bit AVR microcontrollers, which typically has fewer features, fewer I/O pins, and less memory than other AVR series chips. The first members of this family were released in 1999 by ...

    en.wikipedia.org/wiki/Pinning_ceremony_(nursing)

    A pinning ceremony is a symbolic welcoming of newly graduated or soon-to-be graduated nurses into the nursing profession. The history of the ceremony dates back to the Crusades in the 12th century, and later, when Queen Victoria awarded Florence Nightingale the Royal Red Cross for her service as a military nurse during the Crimean War. By 1916 ...

  7. Operational amplifier - Wikipedia

    en.wikipedia.org/wiki/Operational_amplifier

    Pins are labeled as listed above. An operational amplifier (often op amp or opamp) is a DC-coupled electronic voltage amplifier with a differential input, a (usually) single-ended output, [1] and an extremely high gain. Its name comes from its original use of performing mathematical operations in analog computers.

  8. Personal identification number - Wikipedia

    en.wikipedia.org/wiki/Personal_identification_number

    Personal identification number. A personal identification number (PIN), PIN code, or sometimes redundantly a PIN number, is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system. The PIN has been the key to facilitating the private data exchange between different data-processing centers in ...
