Twilight switch to 230V
~
This
twilight switch
using a PIC
12F683 micro
and is powered
directly from the
mains without
traspormatore, so you must
have the
necessary technical skills to avoid
accidents.
The circuit diagram
is divided into
three parts: The power supply,
the micro
and the triac.
The maximum power
manageable is determined by the
triac and the
size of the slopes
of power.
The
micro constantly
acquires the
brightness level from the
photoresistor,
when there is a change
light / dark, or vice versa, the micro
verifies that
this event will last at least
5 seconds before
changing any
exit status.
The jumper
J1 is inserted
into the calibration phase
is suppressed
because if this
is the routine
of the 5 seconds
to immediately verify
the desired
brightness level.
