HOW IT WORKS
REAL WORLD ANALOGIES
The servo is a motor that
can swing back and forth
or be turned to a specific
position.
There are a few accessories
you can use with the servo
(like the mechanical arm).
You can find out how to use
those on pages 16–18.
The servo has two modes.
In
TURN
mode, the input
from other Bits determines
the position of the arm –
try using a dimmer to set
the angle you want. In
SWING
mode, the servo
will move back and forth
on its own like a pair of
windshield wipers – the
input signal controls the
speed of the swing.
The arc of the servo’s swing
is about 110 degrees from
one end to the other.
