Control Stepper Motor 28BYJ-48 Using TTGO T-Display ESP32

Control stepper motor with ESP32 and Arduino.

Introduction

A stepper motor is an electric motor that rotates in discrete step increments. The movement of each step is precise and repeatable; therefore, the motor’s position can be controlled precisely without any feedback mechanism. Nowadays, it is being used widely in 3D printers, CNC machine or laser engraving (like Snapmaker). In this tutorial, I will share the basic steps to control stepper motor movement using ESP32 board.
