Raspberry Pi Stepper Motor Control with L293D / ULN2003A

Raspberry Pi Stepper Motor Control with L293D / ULN2003A | tecno4 | Scoop.it
Stepper motors are ideal for applications where it is necessary to know the angle of rotation, for example in robotics. Unlike a normal motor, stepper motors can control the steps individually and can therefore detect the exact position.
For easy controlling such a motor, a driver IC like the L293D or the ULN2003 are needed. The use of both drivers is shown in this tutorial.

Control a stepper motor with buttons and a Raspberry Pi

Control a stepper motor with buttons and a Raspberry Pi | tecno4 | Scoop.it

This tutorial will explain how to control the 28BYJ-48 stepper tor driven by the ULN2003 stepper driver board in two directions with pushbuttons.


The motor is commonly used in many different applications. This makes it the perfect component for your next project! Some products that contain stepper motors: printers, plotters, slot machines, camera lenses, CNC machines and, more recently 3D printers.
