The motor is controlled via an Arduino Nano and an A4988 stepper motor driver. However, that only covered the mechanical side of things.

So you've already outgrown Arduino's most beginner-friendly board, the Uno, and are looking to move on to bigger, more exciting projects. In that case, the Nano family might just be what you need ...

Then he found the very affordable 28BYJ-48 stepper motor. After some experimenting, he came up with a smooth moving robot arm with four steppers controlled from an Arduino Mega and A4988 stepper ...

Components and Assembly The core components of this project include 3D printer parts, stepper motors, and an Arduino Nano development board.

Arduino projects can help ease the learning curve of getting into programming, and even add some smart functionality to your everyday tasks around the house.
