Digital Alarm Clock

While different types of alarm clocks have been around for years, many people find the concept of the digital alarm clock to be very high tech and futuristic. There’s nothing that is futuristic about them, of course, but they continue to look great. Standard analog alarm clocks often are powered by gears that must be wound on a regular basis. Even those that are powered by batteries usually only have the option of setting the time and setting one alarm. That alarm is usually sounded by a small hammer knocking against chimes on top of the clock.

Digital alarm clocks, however, offer many other options and are usually much more precise than analog alarm clocks. Most digital alarm clocks take two power sources: you can plug them in and you can insert a battery for backup. If power goes out, the battery takes over and keeps your clock operating. If the battery goes out, the electrical outlet will continue to supply power until you put in a new battery. This backup system ensures that you’re never late for work or any other appointment due to power failure.

Another option with digital alarm clocks is to use either 12-hour or 24-hour time notation. Changing back and forth between the two time systems is very easy and often only takes pushing a button. Some digital clocks also feature two different alarm settings, so you can set one alarm for weekdays and another for weekends if you like. Some digital alarm clocks also give you different alarm sound options, and those that feature built-in radios give you the option to have either the alarm buzzer or the radio turn on when the alarm goes off.

Digital alarm clocks make use of LED, LCD, or VFD displays. These displays light up at night, making it easy to see what time it is even in the dark. These displays are actually very inexpensive to create, and they can be very small, too. This means that digital clocks are often inserted into many other devices, including microwaves, car dash boards, computers, cell phones, ovens, and more.

While you may have to reset your digital alarm clock if both the battery and power fail or when daylight savings time occurs, there are some digital alarm clocks that do not require this. These clocks contain a small radio receiver that allows them to synchronize their display with that of an atomic clock or a satellite. This means they will always display the correct time and you’ll never have to worry about resetting them.
