Hi!, I'm glad you found the article useful, the error shown above has nothing to do with the adafruit library or hardware, the problem it's clear in the last line:

zeroDivisionError: float division by zero

that means that the code it's performing a division by zero which is not possible.

Have you changed the simplest.py file? in your code, I'm seeing lines that are not found in the original one.

Edit: I've checked the library and it says that it's' deprecated, maybe that has to do with the problem, either way, I recommend you skip that test and work with the second library I showed in the post, it's simpler and works better.

Hope this helps, let me know how you do.

Hi! Thanks for your answer. I just repeated the tutorial with the second library (--> Adafruit_CircuitPython_ServoKit).

The same kind of error:

I expect you have nothing different running than the stock Raspian? What version of python do you use? Python3.10? I have Python3.7 on the Raspberry Pi, and I do not know how to upgrade it to 3.10...

Your help would be VERY appreciated!
