The stepper motor comes with a pre installed connector that you can directly connect to uln2003 controller.
Stepper motor controller raspberry pi.
Sb new motorshield for raspberry pi 3 2 1 and zero this expansion board can control up to 4 motors or 2 stepper motor 2 ir sensors and a single ultrasonic sensor.
For testing purpose this is not necessary and from easydriver v4 5 the pulldown resistors are on the easydriver board.
You can also connect the pi directly to the easydriver.
Raspberry pi on the other hand is a tiny computer that is being used in a wide range of applications like robotics home automation industrial automation an many other.
In this tutorial i will show you how to setup a stepper motor with a raspberry pi.
