An alarm clock is a device that sounds an audible signal, such as a bell, to awaken someone from their sleep or to serve as a reminder for an event or activity. The first American alarm clock was invented by Levi Hutchins in 1787. More than 100 years later we have gone from bells and chimes to noise-cancelling headphones and sound machine apps for our phones and computers!
The most common type of alarm clock that people use, the one that wakes you up in the morning, is called an analog alarm clock. This type of alarm clock is typically seen as being more reliable because it has a ticking noise to awaken people who are sound asleep.
However, with the advent of new technology, there are also digital clocks that can be set with an on-screen time and date.
If you're like most people, you probably never realized that there are alarm clocks available to use online. The idea of it may seem strange, but in this modern era where many people spend more time on the internet than they do in the living room, it's not surprising that someone finally came up with a way to make alarm clocks online. Moreover, because these alarms are connected to the internet through an app or website, they can be set anywhere and at any time possible.
