PIC16C84 microcontroller has a new technology
semiconductor chip. The microcontroller applicated as
two channel timer in this final project, at reach degree
of university. The microcontroller system has been
designed having two function : timer on/off and real
time using internal timer, and controlling timer channel
one and two.
The method of real time, only using an internal
timer with crystal 4.194304 MHz, divided by internal
prescaler of microcontroller. By programming the
frequency base has been obtained.
The development of this equipment included LCD as
real time and timer display, keypad used as real time or
timer setting, relay - driver to switch on- off the
loads, e.g.: lamps or other electrical equipment. The
result of this project was an microcontroller system
using PIC16C84 which functional test was correct.
