I2C Communication with an Arduino Alex Lange ECE 480 – Design Team 3 November 13, 2015 Arduino, IIC, I2C . Objective: After this, the address of each LCD is entered as well as the pins the I2C module needs to send information to.

I2C Between Arduinos: Maybe sometimes we want to share the workload of one Arduino with another. Or maybe we want more digital or analog pins. Inter-Integrated Circuit or I2C (pronounced I squared C) is the best solution. I2C is an interesting protocol. It's usually us. . .
Arduino Lektion 24: LCD 4x20 Modul mit I2C Schnittstelle
It uses the I2C pins at Analog 4 and Analog 5. It will also work perfectly with Arduino Mega R3's which have the extra SDA/SCL I2C pins broken out. Earlier Mega's have the I2C pins in a different location and will require you to solder two wires from the I2C pins on the shield and plug them into the different I2C locations at Digital 20 21.
LCD Shield Kit w/ 16x2 Character Display - Only 2 pins
To make it easier to make shields which use I2C the manufacturer added the SDA/SCL pins in a known location. For both boards they are connected to the correct pins for that board. A similar remark applies to the later versions of the Mega2560 board. You can use either pins: the ones marked SDA/SCL or the appropriate pins for the board to hand.

Arduino Uno Rev3 - storearduinocc
hares his latest knoledge about I2C: Ever wanted to use any pair of pins for I2C on Arduino, not just the dedicated pins on Analog 4 5? Me too, so I made a quick little Arduino library called “SoftI2CMaster”, available in the “blinkm-projects” Googlecode repository.
Arduino Wiring Test - Adafruit BME680 - Adafruit
2/23/2017No, the I2C is fixed to the specific pins for a ATmega2560 microcontroller. I can think of two things, perhaps someone else can think of a third one.
Use PCF8574(A) I2C GPIO to add more digital pins to Arduino
The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328P (Arduino Nano 3. x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. A SoftwareSerial library allows for serial communication on any of the Nano's digital pins. The ATmega328 also support I2C (TWI
