+// I2C Digital Potentiometer
+// by Nicholas Zambetti <http://www.zambetti.com>
+// and Shawn Bonkowski <http://people.interaction-ivrea.it/s.bonkowski/>
+
+// Demonstrates use of the Wire library
+// Controls AD5171 digital potentiometer via I2C/TWI
+
+// Created 31 March 2006
+
+// This example code is in the public domain.
+
+// ---------------------------------
+// Example from : http://www.arduino.cc/en/Tutorial/DigitalPotentiometer
+// Adapted to show usage of the SoftwareWire library
+// ---------------------------------
+
+
+#include <SoftwareWire.h>
+
+// SoftwareWire constructor.
+// Parameters:
+//   (1) pin for the software sda
+//   (2) pin for the software scl
+//   (3) use internal pullup resistors. Default true. Set to false to disable them.
+//   (4) allow the Slave to stretch the clock pulse. Default true. Set to false for faster code.
+//
+// Using pin 2 (software sda) and 3 (software scl) in this example.
