Once the library has installed, we can start up a Python command line and try a few commands to get the motors running. Type the following command to start an Interactive Python session.

from rrb2 import *
rr = RRB2()
rr.forward()
If you have a very old revision 1 model B Raspberry Pi then change the second line to: rr = RRB2(revision=1)

To stop the motors again, enter the following line:

rr.stop()

To set the motors running forward for 5 seconds, use the command:

rr.forward(5)

To set the motors running forward at half speed enter the following command:

rr.forward(0, 0.5)

As well as forward try experimenting with the commands reverse, left and right, which work in just the same way as forward.
