+//    The original author is not know.
+// Version 2, Juni 2012, Using Arduino 1.0.1
+//     Adapted to be as simple as possible by Arduino.cc user Krodal
+// Version 3, Feb 26  2013
+//    V3 by louarnold
+// Version 4, March 3, 2013, Using Arduino 1.0.3
+//    by Arduino.cc user Krodal.
+//    Changes by louarnold removed.
+//    Scanning addresses changed from 0...127 to 1...119,
+//    according to the i2c scanner by Nick Gammon
+//    http://www.gammon.com.au/forum/?id=10896
+// Version 5, March 28, 2013
+//    As version 4, but address scans now to 127.
+//    A sensor seems to use address 120.
+// 
+//
+// This sketch tests the standard 7-bit addresses
+// Devices with higher bit address might not be seen properly.
