User Manual

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 seconds, 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 don’t 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.
