What is Arduino®

Arduino ® is an open-source prototyping platform based on easy-to-use hardware and software. Arduino ® boards are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino ® software IDE (based on Processing). Additional shields/modules/components are required for reading a twitter message or publishing online. Surf to www.arduino.cc for more information.

Whadda WPM333 Stepper Motor Driver Arduino example
This example shows how the Whadda WPM333 Stepper Motor Driver board can be used with Arduino.
The following connections are required:
2 <==> CW+
GND <==> CW-
3 <==> CLK+
GND <==> CLK-
