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.

While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield.

How to Control a Stepper Motor Using a Computer. Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers.

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB ...

“AnanasStepper is a universal application, advanced motion control stepper motor that adds performance and precision to upgrade and improve any stepper driven machine.
