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.

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 ...

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.

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

Moreover, changing from a stepper motor to BLDC requires a significant redesign of the mechanical subsystems, in addition to developing the control software. These demands can significantly ...
