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.

Numerous machines designed with stepper motors for economic reasons could deliver better user experiences if they were quieter, smoother, and more energy-efficient. New control ...

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 ...

Both the AMIS-30621 and AMIS-30622 integrate a bus connection, positioning and control electronics and a motor driver in a single 32-pin, “near chip-scale” (NQFP) package with a profile of ...
