An alarm clock is a clock that has an alarm, either to wake its owner or remind them of the time. The classic analog alarm clock has an extra hand called a "snooze" hand, which when the alarm goes off, the snooze hand moves around to indicate that it is temporarily turned off.
The invention of the first mechanical clock in Europe is often attributed to Al-Jazari in 1206. His design was driven by water and a weights system. The weight was lifted up by water and as long as it continued to flow, it would turn gears which would drive this machinery. This design became very popular and led many other inventors to create their own versions of mechanical clocks over the next centuries.
We all know how important it is to get up and start our day. And we all know how difficult that can be.
An alarm clock is a device that wakes people from their sleep by making noise or by flashing lights at them. The alarm clock was invented in 1876 by Levi Hutchins of New England, US.
There are two types of alarms: the single-action alarm and the double-action alarm. A single-action alarm has only one button for turning off the noise or light, while a double-action alarm has two buttons: one to turn off the noise or light and one to snooze for a few minutes before the noise or light starts again.
A typical modern digital alarm clock has three main components: a display, an "alarm" button, and one or more "snooze" buttons. Some models have a button to switch between digital and analog displays. Most also have other features, such as FM radio receivers and MP3 players, built in as well.
