io - Connecting multiple devices via I2C - Raspberry Pi
The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino or Genuino Master board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.

You can connect multiple I2C devices, such as ADCs, LCDs, and sensors, to the I2C pins on the Arduino hardware. Each I2C device on an I2C bus must have a unique address. Most devices have a default address assigned by the manufacturer.

2/6/2018multiple i2c devices with arduino #79433. - Thu Dec 06, 2018 10:25 am #79433 HI, i am trying to interface SSD1306 and MLX90614 i2c devices with ESP8266 mcu. but both devices are not working together. . if i comment out code for display then it is working for mlx90614. connect them in parallel. Both SDA and SCL pair to the same pins. mlx
I2C Between Arduinos: 5 Steps (with Pictures)
ultiple i2c can't work with arduino uno. Ask Question 0. I am trying to connect 2 I2C modules to arduino uno. In general, in a system where one device is at a higher voltage level than another, it may be possible to connect the two devices via I2C without any level shifting circuitry in between them. The trick is to connect the pull_up
Running 2 i2c instances simaltaneusly - Arduino Forum
So one can 'ideally' connect 120 devices on the arduino I2C lines. However, other things come into picture here, bus capacitance being one of them. As a rule of thumb,try to keep it below 400 pico Farads. That means 120 devices on these lines can be too much of a load.
Can I connect multiple system into a single Arduino? - Quora
/20/2015Since this device doesn't have address pins, you can only hook 1 device per I2C bus. Re: Connecting multiple I2C devices #18004 By j0hncc - Wed May 20, 2015 9:29 pm

We'll be showing how to connect with an Arduino, for other microcontrollers please see our MCP23008 library code for the commands to send to the i2c i/o expander. I2c is nice because it only uses two pins, and you can put multiple i2c devices on the same two pins.
ltiple i2c devices? GitHub
I2C devices. If something has connectors labelled SDA and SCL, then it is an i2c device that can be accessed using the Wire. h library. You can daisy chain several of these devices together, providing each device has a unique address. Arduino Uno : SDA goes to pin A4, SCL goes to pin A5.
