This is fine enough for most applications. ![]() This method does not allow for micro-stepping, only full steps. Equally true is that a more advanced stepper driver will require at least another pin for direction and they’ll usually have other pins for micro-stepping. As such, this method requires 4 pins from your Pi to drive the Motor Vs only 1 pin with a more advanced stepper driver. There are 2 coils on a bipolar stepper motor, each with a + and a – side. There exist cheap stepper drivers which only require 1 signal from the Pi to be instructed to execute a full step sequence. You are activating the motor’s coils in sequence yourself to have it take steps. ![]() ![]() ![]() This is a rudimentary way to drive a stepper motor.
