Development of microcontroller-based technology is growing
in line with the needs in education, offices, and another - another. in
education as schools are still using manual clock and bell. then
designed a digital clock using a real time clock-based
microcontroller that can automatically adjust the sound of a bell and has a central
hours, so that the digital clock at the school would show the time
the same.
Design and manufacture of this hour include technical issues such as
analyzing hours of admission, rest, and at home in the school, the basic theory
microcontroller, the theory of RTC (Real Time Clock), the basic theory of electronics, and
implement it using codevision avr as a compiler.
By using this hour, is expected to help facilitate
work with school staff no longer need to ring the bell or
hit the bell when time starts to learn, rest, and time to go home. and
provide new knowledge to the students, so students are motivated to
learning about information technology.
