Closed eye of a human, displaying eyelashes which function to catch irritants when the eye is blinked. Blinking also protects the eye from irritants. Eyelashes are hairs which grow from the edges of the upper and lower eyelids that create a line of defense against dust and other elements to the eye. The eyelashes catch most of these irritants ...
A single or a few LED junctions may be packed in one miniature device for use as an indicator or pilot lamp. An LED array may include controlling circuits within the same package, which may range from a simple resistor, blinking or color changing control, or an addressable controller for RGB devices. Higher-powered white-emitting devices will ...
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
A Charlieplexed digital clock which controls 90 LEDs with 10 pins of a PIC 16C54 microcontroller.. Charlieplexing (also known as tristate multiplexing, reduced pin-count LED multiplexing, complementary LED drive and crossplexing) is a technique for accessing a large number of LEDs, switches, micro-capacitors or other I/O entities, using relatively few tri-state logic wires from a microcontroller.
Minibloq + OLPC + Arduino. miniBloq runs under Windows and Linux, in principle, without dependencies. The v0.81 version is distributed both as a Windows installer (exe) or as a single multiple OS compressed file, which contains the Windows and the Linux versions. This last distribution was designed to be portable, so the user can run in from a ...
Blinkenlights on the NSA's FROSTBURG supercomputer from the 1990s Typical LED pattern of a Thinking Machines CM-5. The bits and digits in the earliest mechanical and vacuum tube-based computers were typically large and few, making it easy to see (and often hear) activity.
The corneal reflex, also known as the blink reflex or eyelid reflex, [1] is an involuntary blinking of the eyelids elicited by stimulation of the cornea (such as by touching or by a foreign body), though it could result from any peripheral stimulus. Stimulation should elicit both a direct and consensual response (response of the opposite eye).
