One way of achieving this is to connect the motor into a Transistor H-bridge circuit arrangement. H bridge is an electronic circuit that enables a voltage to be applied across a load in either direction. These circuits are often used in robotics and other applications to allow DC motors to run forwards and backwards (Bi-directional)."
