Driving stepper motors is a perfect example: you can grab a cheap controller board, hook it up to a microcontroller, and the rest is essentially just software.

Symbolic example of quarter-stepping in a bipolar stepper motor. The gradual current and field changes in each microstep cause the rotor to set in intermediate positions. Disturbingly simplified.

A starter kit for the Arduino Uno open-source prototyping board which can be used by professional embedded system engineers and students is available from RS Components, writes Richard Wilson. The kit ...

Mikroe has added a smart 85V 10A stepper motor driver to its range of interchangeable 'Click' boards. Called Power Step 2 Click, the board "is based on ...
