        You can store up to 128 bytes of data on this hub. The data is cleared
        when you update the Pybricks firmware or if you restore the original
        firmware.

Making random numbers

The Move Hub does not include the :mod:`urandom` module. If you need random numbers in your application, you can try a variation of the following example.

To make it work better, change the initial value of _rand to something that is truly random in your application. You could use the IMU acceleration or a sensor value, for example.
