Abstract:
Electronic clocks have predominately replaced the
mechanical clocks. They are much reliable, accurate,
maintenance free and portable. In general, there are
two kinds of electronic clocks. They are analog clock
and digital clock. But digital clocks are more
common and independent of external source. This
system is mainly intended to develop digital clock by
using PIC controlling system. T he microcontroller
based digital clock is constructed with PIC16F628 in
this system . Various types of digital clocks and
modules are available in the market nowadays but
this clock is different at least in the accurate time. To
do controlling in microcontrol ler is only the feature
of the clock. To show the time, 16character × 1line
Liquid Crystal Display (LCD) is used.
