Description Stepper motors are used for CNC machines, 3D printers, and whenever else one needs precise, powerful motion. But to get good behavior from steppers, you need a motor driver chip that can ...

The setup connects the ESP to the four input pins (IN1–IN4) of the ULN2003A, which in turn controls the stepper motor connected to the output pins (OUT1–OUT4). This project helps in understanding how ...
