Connection

Armourbit

Connect the motor to the motor ports on the Armourbit.

Reversing the connection would not damage the motor, but the rotational direction will be reversed.

Robotbit

Connect the motor to the motor ports on the Robotbit.

FAQ

1: The Micro:bit does not react when I click the programming blocks.

Make sure the Micro:bit has been connected to the Kittenblock and then try flashing the firmware.
