Adafruit Motor Shield V2 for Arduino - OpenHacks

The SDA and SCL pins of the GY-521 are used for I2C communication, so these pins must be connected to the SDA and SCL pins of Arduino. The SCL and SDA pins on Arduino Uno are the A5 and A4 pins (look at analog pins) respectively.

How to Connect a Serial LCD to an Arduino UNO: 4 Steps

The Arduino Uno has 14 digital pins – D0-D13. On the Leonardo, these same 14 pins correspond to the same header locations along the side. To gain access to the additional four pins, the first three have been mapped to the ICSP header. SDA/SCL Pins. The pins supporting I2C/TWI used to be the same as analog pins A4 A5. In order to use

Arduino Playground - SoftwareI2CLibrary

The Arduino Uno pinout guide includes information you need about the different pins of the Arduino Uno microcontroller and their uses: power supply, analog and digital pins and ICSP. With I2C there are 2 wires referred to as SCL and SDA. SCL is the clock line which is designed to synchronize data transfers.
