I2C Between Arduinos: 5 Steps (with Pictures)

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.

LCD interface using I2C Module with Arduino - Circuits4youcom

NodeMCU has I2C functionality support on its GPIO pins. Due to internal functionality on ESP-12E, we cannot use all its GPIOs for I2C functionality. So, do tests before using any GPIO for I2C applications. Example. Let’s write Arduino sketch for NodeMCU as I2C master device and Arduino sketch for Arduino Uno as I2C slave device.

Arduino Software I2C user guide - Seeed Wiki

Arduino Software I2C user guide. The standard I2C library for the Arduino is the Wire library. While this library is sufficient most of the time, there are situations when it cannot be used: the I2C pins A4/A5 (or SDA/SCL) are in use already for other purposes;

Arduino et le bus I2C - f-lebdeveloppezcom

The display is connected by utilizing the i2c pins on your arduino. Which pins to use for this differs on some arduino models, but on the UNO and NANO you use pin A4 (SDA) and A5 (SCL).

I2C Communication with an Arduino

The model we’re using here has only four pins and communicates with the Arduino using I2C communication protocol. There are models that come with an extra RESET pin.

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.

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
