MEET THE BIT
Use the motor to spin, turn, twist, and roll.
There are a few accessories you can use with the DC motor
(like wheels). You can find out how to use those on pages
17, 19 and 20.

HOW IT WORKS
The DC (or "direct current")
motor rotates a shaft when it
receives a signal. The more
signal it receives, the faster
the motor will spin.
A switch on the board lets
you choose which direction
the motor spins.
spins
CW
clockwise and
spins
CCW
counterclockwise. When the
switch is in
(variable)
VAR
mode, the amount of signal
the motor receives from
previous Bits allows you
to control the speed and
direction (clockwise or
counterclockwise) of its
motion. In this mode, using
an input like a slide dimmer
makes steering easy!
