Description
A stepper motor is a motor where the turning can be controlled in steps.
Our motor has about 508 steps for 360° (the motor itself has 64 steps but there is a gear train on top)
How to connect it electrically
Required Module and Files
- We use Stepper.py
- this is downloaded from https://github.com/zhcong/ULN2003-for-ESP32
- the original file is at https://github.com/zhcong/ULN2003-for-ESP32/blob/master/Stepper.py

How to control it in MicroPython
import Stepper
from machine import Pin
In1 = Pin(32,Pin.OUT)
In2 = Pin(33,Pin.OUT)
In3 = Pin(25,Pin.OUT)
In4 = Pin(26,Pin.OUT)
s1 = Stepper.create(In1,In2,In3,In4, delay=10)
s1.step(509,-1)
s1 = Stepper.create(In1,In2,In3,In4, delay=1)
s1.step(509)
