    Blink example Power LED (red) and User LED (green) attached to pin 13 on an Arduino-compatible board. Most Arduino boards contain a light-emitting diode (LED) and a current-limiting resistor connected between pin 13 and ground, which is a convenient feature for many tests and program functions. [76]

    As with access codes, there can also be a hierarchy of oral codes, for example, for furnace repairperson to enter the kitchen and basement sensor areas but not the silver vault in the pantry. There are also systems that permit a duress code to be entered and silence the local alarm, but still trigger the remote alarm to summon the police to a ...

    Either the magnitude change or the amount of frequency change can serve to define a proximity distance at which the sensors go from on to off, or vice versa. Common applications of inductive sensors include metal detectors, traffic lights, car washes, and a host of automated industrial processes. Because the sensor does not require physical ...

    en.wikipedia.org/wiki/Microcontroller

    Compilers and assemblers are used to convert both high-level and assembly language code into a compact machine code for storage in the microcontroller's memory. Depending on the device, the program memory may be permanent, read-only memory that can only be programmed at the factory, or it may be field-alterable flash or erasable read-only memory.

    en.wikipedia.org/wiki/STM32

    The following boards have Arduino Nano pin-compatible male pin headers with 0.6-inch row-to-row DIP-30 footprint, but these boards have 3.3 volt logic I/O, instead of 5 volt logic I/O for an Arduino Nano. Blue Pill board has a STM32F103C8T6 microcontroller. [52] [53] [54] Unfortunately, most blue pill boards now contain a fake STM32 from China ...

  9. Smart meter - Wikipedia

    en.wikipedia.org/wiki/Smart_meter

    The term smart meter often refers to an electricity meter, but it also may mean a device measuring natural gas, water or district heating consumption. [1] [2] More generally, a smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor.
