The Arduino Opta micro programmable logic controller (PLC) provides a unique entry point into the automation field. Automation fields like smart homes, process controls, and robotics are project areas ...

Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much ...

My small cnc mill project needs motors (so I am told) that are too powerful for the normal drivers included on grbl Arduino shields (or integrated Arduino+drivers equivalents), and so I have been ...

Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...
