Arduino and I2C Tutorial by Dejan âą âą Arduino Tutorials In this tutorial we will learn how the I2C communication protocol works and also we will make a practical example of it with the Arduino Board and a sensor which uses this protocol. You can watch the following video or read the written tutorial below. Overview
Arduino I2C and Multiple Slaves 8 Steps Instructables
system April 21, 2008, 6:58am 1 Has anyone ever made an Arduino as a Slave I2C ? I'm planning to use 2 minis as slaves connected to a master Arduino (main cpu + lcd & ethernet). Is there anything specific I should be aware of ? like I2C address settings or what ever ? Tnx.. kg4wsv April 21, 2008, 11:35am 2 It's fairly straightforward.
I2C â ArduinoESP32 2.0.14 documentation
When I adjust the potentiometer connected to the Master Arduino UNO, it captures the analog reading from the POT, converts it into a digital value (in the range of 0 - 1023), maps it to a proper PWM value (in the range of 0 - 255) and transmits this value to the Slave Arduino over I2C Bus. The Slave Arduino, upon receiving the PWM Value.

The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Master board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.
Pin on Arduino
Step 1: Circuit Overview. The circuit couldn't be simpler. All you need to do is connect up the Master and Slave devices as shown above, remembering to link common grounds together. A4 on the master is connected to A4 of the slave. The same is true for A5. Here; A4 is I2C SDA. A5 is I2C SCL.
ESP32 I2C Communication Set Pins, Multiple Devices Interfaces and
Slave Devices Each slave device has an I2C address that is used to identify the device. The I2C address makes it possible for a master device to send data to a particular slave device on the bus. Master Devices Master devices can send and receive data. Slave devices respond to whatever a master device sends.

1 Answer Sorted by: 0 An Arduino can be both a master and a slave. Nick Gammon's page on I2C describes how to do it. http://www.gammon.com.au/i2c Communicating with other devices So all this I2C stuff is great, you can use just two wires (plus ground) to talk to up to 119 devices.
example i2c arduino master and slave communication
I2C is intended for short runs, usually less than one meter. If the distance is much longer then RS485 adapters and software serial on the slaves will work but the baud value should be 38400 or less. If each MPU6050 has it's own slave Arduino, Nano or Pro Mini, then multiplexing is not needed.
Master Slave I2C Connection Hackster.io
Arduino Uno X2: I used one Arduino Uno as I2C Master and the other as I2C Slave. Once the master/slave code was tested, I then used the Slave Arduino to program the plain ATmega328 microcontroller.
I2C Master Slave Communication between two Arduino board
I2C Slave Mode. The slave mode, the clock is generated by the master device and responds to the master if the destination address is the same as the destination.. To start using I2C as slave mode on the Arduino, the first step is to include the Wire.h header to the scketch. #include "Wire.h" Before calling begin we must create two callback.

An I2C slave project built on top of the Wire.h library. Designed to easily drop into a variety of projects which can then be managed by an I2C master. This project uses a combination of an in-memory array and EEPROM as the I2C registers. The in-memory array by itself is obviously volatile and unsustainable across device restarts.

Follow these steps to connect two Arduino UNOs using I2C: Connect pins A4 and A5 on one Arduino to the same pins on the other one. The GND line has to be common for both Arduinos. Connect it with a jumper. In case of any doubt, consult the circuit diagram given below. NOTE: Remember never to connect 5 V and 3.3 V Arduinos together.

I2C is truly a powerful option of Arduino, for too many reasons; yet the amount of tutorials available are not that many and unfortunately are too complicated for the average person. After working on this for 2 days, I think I have a way to transfer pretty much anything between master and slaves and viceversa.
