Design of Digital clock based on MCU
Abstract
In recent years, SCM has been applied in many fields. Whether in industry or in life,
many products are controlled by the microcontroller. SCM to its small size, low power
consumption and high performance widely loved by the people.
This paper combined with a microcontroller core some related peripheral devices
(LCD, keypad circuit, reset circuit, alarm circuit) and use the appropriate software to
achieve the purpose of making a digital clock, a digital clock in our daily lives application
is very wide, it can be everywhere. Time to look for work, meetings depends on time,
industrial production depends on time, so we can be described as a very important time for
sure.
The design of the digital clock requires the ability to display real-time clock, can
display year, month, day, hour, minute, second, and real-time temperature also features
remote communications. Difficulties in the hardware part is that the selection, placement
and soldering components.
