Manually controlling bipolar stepper motor with Arduino and EasyDriver

Stepper motors are great for accurate positioning because they move in discrete steps – a feature that makes them very appropriate for CNC software control. But every once in a while you have an application where you need to press a button and rotate some kind of a jig at a preset angle or move something a preset distance if it’s a stepper-driven linear stage. So, I decided to modify an earlier Arduino sketch I wrote for testing the world’s smallest stepper motor to make it a bit more useful (and clean any bugs in the process). Keep reading to see what came out … Read the rest of this entry »

World’s Smallest Stepper Motor with Arduino and EasyDriver
This little wonder of electromechanical engineering came from inside a laser diode sled of an HP CT10L Bluray drive I’ve opened some time ago. The device on the picture consists of several parts, all easily fitting on a dime coin: a bipolar stepper motor with lead screw, a linear stage, a lens, and even an end position sensor (I’ve yet to make use of the sensor though). The entire assembly is only 14mm x 9mm x 4mm. This post is about making this tiny motor move. Keep reading! Read the rest of this entry »
