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.

Learn how to build a Arduino Opta DC motor controller with a pushbutton switch and a programmable human machine interface (HMI).

grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

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.

That’s the idea behind [BetaChecker’s] two-axis stepper motor, which looks like it has a lot of potential for some interesting applications.
