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.

Rotary encoder decode for Arduino It is amazing how many Arduino programmes for decoding rotary encoders start with something like: “I looked at all the available rotary encoder sketches and none of ...

Relative and Absolute are two primary types of rotary encoders. A quadrature encoder is in the relative encoder family and is most commonly used in high-speed motor control systems; it also ...

Advanced internal current sensing provides better current regulation in bipolar stepper motor drivers, which improves the quality of motion.

How optical rotary encoders can provide real-time motion feedback on motion applications using stepper motor-driven linear actuators.

Rotary optical encoders Rotary optical encoders, the most widespread encoder design, consist of an LED light source, light detector, code disc, and signal processor.

Two-chip designs combining a microcontroller or DSP with a highly integrated driver IC simplify the design of a stepper-motor controller, while also enabling sophisticated control features that ...

Try it out the next time you need to read a quadrature encoder for a motor! The PIO is one of the more interesting pieces of functionality in the RP2040 and it’s great to see it used in a such a ...

This article talks about controlling a basics motion control system, a stepper motor or servo with a driver or amplifier in between the controller and motor, using pulse signals.
