LITTLEBITS LittleBits DC Cross AxelThe DC (or direct current) motor rotates a small shaft you can attach anything to. Try attaching a wheel! Use it to spin turn twist and roll. HOW IT WORKS The DC motor rotates a shaft when it receives a signal. The more signal it receives the faster the motor will spin. Click the arrow to the right to learn more about how it works! A switch on the board lets you choose which direction the motor spins. CW spins clockwise and CCW spins counterclockwise.
