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 26 and 27.
The servo has two modes. In
TURN mode, the input from
other Bits determines the
position of the hub – 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 servo's range of motion
is about 110 degrees.
