3. INTROUDUCTION OF DIGITAL CLOCK
 A digital clock is an model version
to a traditional analogue clock.
 This type of clock shows numbers
to display the time in a digital
format, such as on a watch, phone
or an alarm clock.
 This can be in both 12 and 24-
hour formats, so it’s important for
children to understand before
introducing them to a digital
clock.

4. HOW TO SEE TIME IN DIGITAL CLOCK
 Here is some following steps to see time in digital clock.
 The first two numbers dictate the hour.
 The second two numbers dictate the minutes of the hour.
 Digital clocks can use 12-hour time or 24-hour time.
 If they are using 12-hour time, they may include the letters AM
or PM to signal whether it is the first half of the day or the
second half.

5. HISTORY OF DIGITAL CLOCK
 The first digital alarm
clock was invented by D.E.
Protzmann in the United
States in 1956 and after
that.
 Thomas Bromley, an
engineer and created
his Digitron Electric
Clock in 1961 at his home
in Hull.
 It was made by Tube.

6. SOME OLDEST DIGITAL CLOCK
1. Nixie Tube IPS Vintage Digital Alarm
Nixie Tube IPS Vintage Digital Alarm Clock, It is 6
Bit RGB Glow LCD Time Photo Display, DIY Nixie
Tube Clock Simulation, 12 and 24 Hours
Display,5V USB Creative Retro Desk Decoration.
2.Aged digital clock with thermometer
This Extech Hygro-Thermometer Clock
simultaneously displays humidity, temperature and
clock time, set for either 12 or 24 hours. A memory
function stores minimum/maximum measurements for
both temperature.

7. METHOD TO MAKE DIGITAL CLOCK
 Here is some following steps to see time in digital clock.
 Draw the Circuit Diagram for the Clock.
 Simulate the Circuit.
 Design the PCB and Order.
 Solder All the Components on Board.
 Set the Proper Time/Date in the RTC IC.
 Do Required programming by programming language like
JAVA,C++ .
 Upload the Code in the Microcontroller.
 It is ready to use.

8. ADVANTAGE OF DIGITAL CLOCK
Less Expensive so anyone can buy easily.
Easy to understand time concept.
Give time accurate than Analog clock.
Easier to Read Time.
More visible and change any color.
It use LCD and LED Display.
Easy to set Timer.
Easy to set Time.

9. APPLICATION OF DIGITAL CLOCK
It uses in different Devices like:-
1.Cars
Digital clocks in cars provide a simple yet essential
feature that enhances the driving experience by
providing accurate timekeeping, Alarm and
reminders functionality.
2.Radio
 Basically, the digital clock serving as a timer to turn
the radio on or off at a preset time.
2.Mobile Phone
A digital clock on a smartphone serves several
purposes like Accurate Timekeeping, Alarm , Timer,
stopwatch and Integration with other apps.

10. CONCLUSION
 They offer unparalleled accuracy,
convenience, and versatility, making
them an essential part of modern life.
 Displays time using numerical digits
(example:- 4:05) on a digital screen,
typically using LED, LCD
technology.
 Digital clocks make it easy to see the
time so a children can also see time
easily and do work easily.
 It consumes less power than analog
clock so it cheaper than analog clock.
