+// by Nicholas Zambetti <http://www.zambetti.com>
+
+// Demonstrates use of the Wire library
+// Sends data as an I2C/TWI slave device
+// Refer to the "Wire Master Reader" example for use with this
+
+// Created 29 March 2006
+
+// This example code is in the public domain.
+
+
+#include <Wire.h>
+
+void setup()
+{
+  Wire.begin(2);                // join i2c bus with address #2
+  Wire.onRequest(requestEvent); // register event
+}
+
+void loop()
+{
+  delay(100);
+}
+
+// function that executes whenever data is requested by master
+// this function is registered as an event, see setup()
+void requestEvent()
+{
+  Wire.write("hello "); // respond with message of 6 bytes
+                       // as expected by master
+}
