ABSTRACT
A digital clock is a circuit that is designed in such a way that it resembles a clock that
has a more precise indication of the number of seconds. By using the digital clock method, it
can be expected to overcome the problem of time differences, where using a wall clock still
uses the manual method to match the hour and minute hands on each wall clock.
The digital clock system is equipped with an Arduino Uno microcontroller, Real Time
Clock (RTC), and a 16x4 LCD. Where the Arduino Uno microcontroller acts as a controller
on a programmable device system connected to a computer, Real Time Clock (RTC) as a time
generator, and a 16x4 LCD to display the time and date.
