Driving a brushless DC (gimbal) motor can be a pain in the transistors. [Ignas] has written up a nice article not only explaining how to do just this with an Arduino, but also explaining a little ...

Unlike most other DC motor driver modules, this module has a single VCC for both ... Even though it’s easy to use a microcontroller like Arduino to test the module, I simply rigged a circuit for that ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into ... the ‘stepper motor driver’ interface pins hooked up to the motion controller upstream. The Arduino source for ...
