Fits a Sharpie
TM
Fits a pen
MEET THE ACCESSORY
The mechanical arm
attaches to both the servo
hub and the DC motor shaft,
and offers lots of leverage
for pushing, pulling, and
throwing.
HOW IT WORKS
To attach the mechanical
arm to the servo hub,
use two of the #6 screws
(included) and a Phillips­
head screwdriver (not the
purple screwdriver). Be sure
to screw through the holes
on the servo hub.
To attach the mechanical
arm to the DC motor, line up
the flat edge of the DC motor
shaft with the flat edge of
either of the flat­edged holes
­sized marker
on the mechanical arm.
The two large holes on the
end are perfect for holding
pens and markers in place.
a24 SERVO MOUNT
Connect to servo hub
with included #6 screws
MEET THE ACCESSORY
The servo mount lets you
attach your servo to a
mounting board or a pair
of littleBits shoes. It's a great
way to keep the servo steady
so the arm can go wild.
HOW IT WORKS
Push the servo in from the
side until it clicks into place.
To keep the servo from
sliding up and down, use
the included screws and a
Phillips­head screwdriver.
