2. To
make
an
IR
gun
we
need
a
remote
control
and
a
toy
gun
3. On
the
other
hand
we
need
a
IR
receiver
and
a
Arduino
breadboard
4. A=er
installing
the
IR
library
for
arduino
and
making
the
IR
receiver
work
we
push
a
bu@on
on
the
remote
control
and
look
which
bu@on
we
can
receive.
And
we
write
down
the
code
we
receive
(A81
in
our
case).
