 You're familiar with the first few lines; in fact, the only lines you may not be familiar with are the `r.motor_boards...` lines. For a comprehensive reference to the `motor` object, see [`motor` API](/api/motor-board) page.

 Now we're going to modify the program to vary the speed of the motor. Our aim is to do the forwards and backwards bit (as above), but, before we loop round again, ramp the power up to 70%, then down to -70%, and then back to 0 (all in steps of 10%). Here's the code:
