L9110 with Arduino Code – Part 3: How to Stepper Motor Speed and Direction

This video is the third part of the tutorial where I will discuss how to use small stepper motors such as this NEMA-17 with the L9110 motor control board using Arduino. I will also explain how to perform micro stepping and prevent your stepper motors and control boards from overheating.

This board can be used to control two small DC motors simultaneously or can be used to control a small stepper motor, such as a NEMA 17. The board operates between 2.5- and 12-volts DC. It is capable of sourcing 800 mA per phase sustained and 1.5 Amps momentarily.

This tutorial is divided into 3 videos. Part 1 covers the speed and direction control of DC motors. Part 2 discusses the control of linear actuators. Part 3 demonstrates how to control the speed and direction of stepper motors. Each video includes step-by-step set-up instructions as well as basic Arduino coding that can be incorporated into your own projects.
