The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. It is one of the most popular timing ICs due to its flexibility and price.
Hans R. Camenzind (Swiss Standard German: [ˈkaːməntsɪnd]; 1 January 1934 – 8 August 2012 [1]) was an electronics engineer known for designing the 555 timer IC in 1971 under contract to Signetics. [2] He was the inventor on 20 US patents.
A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
Note: 555 timer IC#Pinout writes them exactly how I want...a fully-spelled one-word name for each pin in all caps (except GND and VCC cause those are standard abbreviations). Em3rgent0rdr 02:59, 14 July 2022 (UTC) another inconsistency that is bugging me is how sometimes the trigger pin is written without a line over it but sometimes is.
The Intel 8253 PIT was the original timing device used on IBM PC compatibles.It used a 1.193182 MHz clock signal (one third of the color burst frequency used by NTSC, one twelfth of the system clock crystal oscillator, [1] therefore one quarter of the 4.77 MHz CPU clock) and contains three timers.

Time for Timer is a series of seven short public service announcements broadcast on Saturday mornings on the ABC television network starting in 1975. The animated spots feature Timer, a tiny cartoon character who is an anthropomorphic circadian rhythm , the self-proclaimed "keeper of body time."
A typical kitchen timer. A timer or countdown timer is a type of clock that starts from a specified time duration and stops upon reaching 00:00. An example of a simple timer is an hourglass. Commonly, a timer triggers an alarm when it ends. A timer can be implemented through hardware or software.
