+3. Take a look at the diagram below, you will see that the motor takes almost 2000 milliseconds to move through 180°. Add a pause after the ``angle`` variable has been reset to 0. This is so that the micro:bit will wait for the motor to move to angle 0° before moving it again.

+5. Experiment with the duration of the pauses until you have a smooth motor motion.
