Going with a Polulu Tic 500 instead of an MDD3A, which doesn't have current limiting. I could only get the stepper motor to make noises or jolt even after a reasonable amount of troubleshooting, trying PWM, MicroPython, Arduino code, and a variety of examples. If I come back to this, use of PIO (e.g., https://danielwilczak101.medium.com/introduction-to-programmable-input-output-pio-using-raspberry-pi-pico-example-code-included-af4eb9abfe86) may be the way to go.

However, a general preference might be to use things that support I2C and have companion libraries. Here are some examples for the Polulu stepper controllers:

• https://github.com/jphalip/ticlib (probably the best one to use)
• https://www.pololu.com/docs/0J71/12.10
• https://github.com/AllenInstitute/pytic

As an aside for the automated turntable, a stepper servo would probably provide better positioning.

I.e., support multiple Python packages, but under the same parent repository/package. The alternative is to package everything under a single Python package, or to separate out the Python packages into separate repositories. This will affect the scope/intention of the ac-training-lab repo in terms of usage/installation by others.
