Hi.
Make sure you’ve installed micropython on your board and that the computer is connected to the board.
Also, make sure you have the correct board and interpreter selected at the bottom right corner.~

The machine module is automatically isntalled when you install the Micropython firmware on your boards.

Regards,
Sara

Not working! Where did you get the machine library from?

Thanks for this code.

I have a question:

In the _step function in stepper.py the current position and state are update after the
gpio pins are set. This seems to me to leave the position and state how they will be after
the next step not after this step. Am I missing something here.

Also have you tested the step_degrees function. I get a zero not defined.

Thanks

Just what I was looking for to use in a rotary turn table I’m making for making videos.

Thanks!

Hi.
Yes.
You can do it via http or MQTT.
We have this getting started guide for MQTT with the Pico: https://randomnerdtutorials.com/raspberry-pi-pico-w-mqtt-micropython/
