Arduino Pinout Reference说明书
This 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 ...
TWI: A4 or SDA pin and A5 or SCL pin. Support TWI communication using the Wire library. The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possi...

1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which...
TWI:Pin 20 (SDA) and 21 (SCL) support TWI communication using the WIRE library. AREF:The reference voltage for analog inputs is used with analogReference(). Reset:for this pin bring the reset line LOW to reset the microcontroller. This pin is typically used w...
Analog pins A4 (SDA) and A5 (SCL) support I2C (TWI) communication using the Wire library. This library can be used to communicate between the Arduino Nano and sensors, displays, other Arduino boards, etc.In the table below, you can find the I2C pins of some of the other Arduino boards...
