How to use multiple i2c devices on the same bus with the Arduino

I wire and program two i2c devices on the same i2c bus with the Arduino as the master.

Straight and simple.

Thanks. This is exactly what I needed. (Note: pull up resistors its already there) .

The data and clock pins on every I2C device is pulled up?

Use the photon-pixel coupling method, it is a new approach in science for reading an unlimited number of sensors in parallel. Maybe you can do it with an Arduino. From what I know it supports a cam.

Awesome. I also need to connect a display and rtc for a project. Now I know how. Thanks!

nice video! I was searching for this as I'm also going to use an RTC i2c with a i2c LCD. BTW, just wanted to point out that most of the i2c devices boards already have the pull-up resistors on them so no need to wire that.

I also i wanted to do same but does Arduino uno board comes with pull-up resistors ? I really didnt understand how to do this whole shit. It would be really helpful if you give me a short summary for connecting multiple i2c device rtc module and a display

can you please send the code

Why do you need pullup resistors?.... when you can do it with code.... "pinMode(PIN,INPUT_PULLUP)"

We dont need pull up resistors its already their on the modules i think

I'm sorry, I'm hard of hearing. What size resistors did you say you were using for pull up resistors?

@Lukasz420 Жыл бұрын

two 10K value resistors

@ecsyntric 20 күн бұрын

since SCL and SDA are supposed to be common to all devices why not put the yellow and blue wires into the open power rail on the other side? unless both power rails are already connect together internally

can you share the codes ?

I’m trying to use two of the exact same sensor. Have you ever done that?

so I am frying displays, is it because I am not using pull up resistors?

@torchwork8651 9 ай бұрын

I would guess no. The resistors are for signals I think.

@tristunalekzander5608 4 жыл бұрын

What kind of resistors are those?

This would have been a great tutorial if you had just explained the resistors.

The OLED is really flickering. I've used OLED before, singly, and no flicker like that. Suppose it's because it's sharing the I2C? Probably so.

@Garan Carter-Woodgate That OLED works at 3.3V no? Hooking it with 5 V supply would wreck it no?

Maybe you shouldn't be doing this if you don't know what a pull-up resistor does! Doesn't give much confidence that you actually know what you are doing.

You do it then. Starting a KZfaq channel is free. Do it
