So he started to wonder if he could skip the controller entirely and connect the stepper motor directly to the digital pins of an Arduino.

How to Control a Stepper Motor Using a Computer. Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers.

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 ...

AMI Semiconductor, a manufacturer of integrated mixed-signal and structured digital products, has introduced two single-chip stepper motor controller ICs.

The FTDI DLP-USB245M is a USB-to FIFO interface module that simplifies the control of multiple steppers by a PC.
