MEET THE BIT
o11 SERVO
The servo is a motor that can swing back and forth or be
turned to a specic position.
There are a few accessories you can use with the servo (like
the mechanical arm). You can nd out how to use those on
pages 18 and 19.
The servo has two modes. In
TURN mode, the input from
other Bits determines the
position of the hub – try
using a slide 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 servo's range of motion
is about 110 degrees.
