Viewer stopwatch and MICROCONTROLLER BASED DIGITAL CLOCK AT89S5 1

ARY SUPRIYANTO

Abstract


In this scientic writing will be
discussed regarding the design of a stopwatch and a viewer-
BASED DIGITAL CLOCK AT89S51yang microcontroller
designed for appear stopwatch and digital clock. Micro-
controller is a single-chip computer that has the ability to
be programmed and used for control-oriented tasks. Space
control is minimal makes the microcontroller is more eec-
tive than with a PC computer, because the microcontroller
has the same architecture with a PC computer. With a 4
port 8 bits as input / output. From the results of experi-
ments performed, the viewer tool stopwatch and clock with
digital display using microcontroller AT89S5 1 may work as
expected. When the key switch 1 is pressed then the stop-
watch will start chopping, and when the button is pressed
the reset switch and a mode at the same time it will go well
designed with 8 pieces of seven segments that will display
the output of the stopwatch and digital clock. Penamaan
