+
+
+#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
+}
