Library's collection Library's IT development CancelIn this final project, Microcontroller MC 68705 R3 has been used as CPU
in counting and time recorder. To follow that function required a base time that
will be use for counting. IC 8253 Programmable Interval Timer has been choose
to provide a base time that required by circuit. By using its mode, IC 8253 can be
use as counter.
The designed circuit will transfer the data every 8 hours. For that reason
DS 12887 Real Time Clock ( RTC ) has been choose to follow the condition.
How circuit work is, firstable to take base time that achieved by sensor reading to
the target 1 and then target 2 respectively.
The process is started by comparing base time to the time that achieved
from sensor that reading the following target. In the laboratorium test proved that
Microcontroller MC 68705 R3 can be implemented as CPU in counting and time
recording. And finally accumulation of the time recorder and counter be printed
and will be use for other interest.
