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. Generally speaking this is a bad idea, but if you’re ...

The idea behind the project is simple: take a stepper motor, put a needle on it, and connect it to an Arduino. Instant analog gauge, measuring anything an Arduino can calculate. The motor used in ...

Stepper motors are a mainstay in precision control systems, valued for their simple open-loop operation and high torque at ...
