This tutorial shows you how to control a stepper motor with a ULN2003 to send it to any angle, direction, and speed using an ESP32 MCU over Wi-Fi from a desktop and from a mobile phone. We can define an unlimited number of angle push buttons and also a custom angle. All the texts are customizable, so you can use them for other languages or other purposes. Your Arduino IDE (the software) must be ready to work with the ESP32.
