3. Have
you
ever
imagined
how
the
street
lights
are
turned
on
in
the
evening
and
they
automa4cally
go
off
in
the
morning?
Is
there
someone
who
comes
early
in
the
morning
to
turn
off
these
lights?
Or
imagine
a
situa4on
when
there
is
a
power
cut
and
you
are
searching
for
candles
and
match
s4cks
and
another
situa4on
when
a=er
a
power
cut
your
lamp
glows
automa4cally.
The
following
circuit
based
project
can
help
to
make
your
own
automa4c
night
lamp.
When
the
circuit
is
taken
into
light,
the
resistance
of
LDR
decreases
due
to
which
the
base
voltage
decreases.
The
voltage
becomes
so
low
that
the
base
emiGer
junc4on
is
not
forward
biased
due
to
which
the
transistor
turns
OFF.
Hence,
the
LED
doesn’t
glow.
On
the
contrary,
when
the
circuit
is
taken
into
dark,
the
resistance
of
LDR
decreases,
due
to
which
the
base
voltage
increases
and
a
point
comes
when
the
base
emiGer
junc4on
gets
forward
biased.
As
a
result,
the
transistor
turns
ON
making
the
LED
glow.
