How a Digital Travel Alarm Clock Works

How it Works

Chances are that you will have had a digital travel alarm clock at least somewhere in your home, and probably one that you take along with you on your travels as well. First you should know that every digital clock has a few required components, such as a source of power to run the clock such as batteries or electricity with a plug-in.

It also needs an accurate timebase that acts basically as the clock’s heartbeat, a way to gear down the timebase to extract different components of time, and a way to display the time, which typically these days means using an LED display.

Remember that with a digital travel alarm clock, these functions are taking care of electronically rather than mechanically. This means that it will be a lot more convenient for you because you will not have to worry about constantly taking care of these things.

Now if you want to build your own digital travel alarm clock, you now have a better understanding of all the components involved which is going to be necessary when you want to build something like this. The first thing you need is your power supply, and you are also going to need some capacitors, pidge rectifier, AC transformer and other pieces.

Using a circuit diagram is going to be very important here, and this will help you to keep track of what part of the process you are at, keep track of what you are doing. The number of chips, resistors and LEDs that you are going to need is going to depend on how many digits you want to implement. For instance you may only want to have seconds on your timer, or you may want minutes and seconds, or hours and minutes and seconds, and so on.

You are going to have to make a few important decisions here but afterwards you can be very proud of what you have created with this digital travel clock.
