Playing the guitar requires speed, strength, and dexterity in both hands. Depending on your mobility level, rocking out with your axe might be impossible unless you could somehow hold down the strings ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Allegro MicroSystems has unveiled a 40 V motor driver IC capable of driving one stepper motor and one DC motor. The bipolar stepper driver outputs are rated up to 1.6 A and the high current DC driver ...

The project drives a bipolar stepper motor with the use of a dual H-bridge IS such as the SN754410. The bipolar stepper motors are usually identified on most steppers with 4 wires. Measuring the ...

First, we want to explain how such a controller works and what’s involved. A bipolar motor has two windings, and thus four leads. Each winding can carry a positive current, a negative current or no ...
