The Evolution Of The Digital Alarm Clock
Remember back in the old days, when you had to get up for school? Maybe your mom woke you up, but maybe you had an alarm clock with a bell on the top that would ring. That clock had a face with three hands: an hour hand, a minute hand, and a hand to show what time the alarm was set for. Bet you miss those days....No? From those days - and even earlier - to the atomic digital wall clocks available now, the digital alarm clock has gone through many changes.
A Bit Of Digital Alarm Clock History
The very first alarm clock was a very personal one. It was invented by a man named Levi Hutchings in 1787, to wake himself up for work at 4 am. It wasn't until 1847 that someone else was able to patent an adjustable alarm clock. (That was achieved by Antoine Redier, a French inventor.) Both these devices, however, were of the analog variety, as digital alarm clocks were a long time from being invented.
Analog alarm clocks feature the face and hands, and a bell on top, as you probably recall. The time and alarm time were set by turning a knob on the back. Digital clocks didn't come along until 1956, a relative late-comer to the party.
And digital clocks with alarms came even later. But current digital alarm clocks can do much more than just tell the time and ring the alarm bell! Now, most digital alarm clocks also include a radio, and all offer other styles of alarms, like buzzing, beeping, or even music. The owner can adjust these features, setting the digital alarm clock to awaken him with music or buzzer.
Also, since many of us don't really want to get up when the alarm goes off, most digital alarm clocks also have a "snooze" button. If the sleeper pushes the button, the alarm will go off and then back on again after a certain amount of time - like 10 minutes. Usually, that button can be pressed over and over as needed - but be careful when using that feature!
Digital alarm clocks will also help one get to sleep now, offering a "sleep" button, so that the music can play for a certain amount of time while the person is falling asleep. Usually, this can be set for up to an hour, but often allows segments of 15 minutes as well. Alarms are getting more useful, being wherever we are - they are now found in computers and cell phones. Who knows what the future holds?
