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.

Example
| This is an example of how to connect the WPI401 to the WPB100. An additional power
supply is advised to power the motor. |
// This Arduino example demonstrates bidirectional operation of a
// 28BYJ-48, using a WPI401 – ULN2003 interface board to drive the stepper.
// The 28BYJ-48 motor is a 4-phase, 8-beat motor, geared down by
// a factor of 68. One bipolar winding is on motor pins 1 & 3 and
// the other on motor pins 2 & 4. The step angle is 5.625/64 and the
// operating Frequency is 100pps. Current draw is 92mA.
////////////////////////////////////////////////
//declare variables for the motor pins

int motorPin4 = 11; // Orange – 28BYJ48 pin 4
// Red – 28BYJ48 pin 5 (VCC)
int motorSpeed = 1200; //variable to set stepper speed int count = 0; // count of steps made
int countsperrev = 512; // number of steps per full revolution
int lookup[8] = {B01000, B01100, B00100, B00110, B00010, B00011, B00001, B01001};
