// Version 1
|

// This program (or code that looks like it)
|

// can be found in many places.
|
||||
// For example on the Arduino.cc forum.
|
||||
// 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.
