The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

Ok, I lied. This is more of a "do my math" request than a question. I'm working on a project that requires lifting a 10 lb load vertically using a lead screw (threaded shaft) and then lowering it ...
