This example ramps motor 1 speed from zero to max speed forward, to max speed reverse, and back
to zero again over a period of about 3 s, while checking for motor faults and periodically printing the
motor current to the serial monitor. It then performs the same process on motor 2 before repeating all
over again.
Note:
Even if you do not have any motors yet, you can still try out this sketch and use
the motor indicator LEDs for feedback that the shield is working properly.
