Im Erik Bartmann "Die elektronische Welt mit Arduino entdecken" Ist sogar noch ein Fehler, wo Analog In 4 & 5 eingezeichnet ist, was mir spanisch vorkam
I2C: analog input pins A4 (SDA) and A5 (SCL). Support I2C (TWI) communication using the Wire library.
Wire LibraryThis library allows you to communicate with I2C / TWI devices. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to the AREF pin and the additional one is on pins 20 and 21.As a reference the table below shows where TWI pins are located on various Arduino boards.Board I2C / TWI pinsUno, Ethernet A4 (SDA), A5 (SCL)Mega2560 20 (SDA), 21 (SCL)Leonardo 2 (SDA), 3 (SCL)Due 20 (SDA), 21 (SCL), SDA1, SCL1
