Standalone version of the Stepper library provided with AdvancedFirmata.
FirmataStepper controls bipolar and unipolar stepper motors in both two-wire and four-wire configurations. It can also control step + direction drivers such as the EasyDriver.
The library also supports acceleration and deceleration of the motor.
Clone or download and copy FirmataStepper into your Arduino libraries directory. Open in the Arduino IDE, select File -> Examples -> FirmataStepper and select one of the examples.
If you download rather than clone this repository, rename the folder to "FirmataStepper" after unzipping and before copying into your Arduino libraries directory.
