Could you use range(len(kit.servo)) here? Then you can drop the warning note...

@sommersoft The suggestion works! However, only makes sense if you're working with the exact number of servos as there are channels on the board. So if you connect 4, and say range(len(kit.servo)) it'll work, but it's sending data to unused channels.

Maybe it doesn't matter?

It shouldn't, except to add time to overall loop.

Like I said, its an option, but guards against any out of range occurrences. If you'd rather leave it as is, that's ok too.

kit.servo[i].angle = 180
time.sleep(1)
kit.servo[i].angle = 0
time.sleep(1)

Same as above...

Once more for good measure? 😄

kit.servo[i].angle = 0
