28BYJ-48 StepperMotor

Python3 driver to control the 28BYJ-48 stepper motor for RaspberryPi3 platform with ULN2003.

Getting Started

The main function in StepperMotor class is rotate : You can control the rotation of the motor with direction and angle.

• direction: Clockwise = True (default) | Inverted = False
• angle: integer in degrees, can be more than 360 for several rotations.

See example at the end of the code...

Prerequisites

2 modules are needed to make it works:

• RPi.GPIO module to control GPIOs
• Numpy to manage list rolling for phase control.

remi-ma, what else...

What's next

For now on, you can control stepper motor with direction and angle, but we could add:

• if KeyBoardInterrupt, go back to inital position before cleaning up GPIO.
• Phase sequence can be rolled but cannot be changed... but is it useful?
