Hi Arduino-Developers!

i found a bug in the documentation of the MasterReader-Example (which caused several hours of bugfixing :grin: .

In the text, the pins for SDA and SCL are interchanged - this does not matter, when connecting two UNOs, with the same PIN-assignments, but will cause problems, when connecting different types of boards. PIN4 is SDA, and PIN5 is SCL! In the example for the MasterWriter it's correct.
