Sending Data via I2C (RaspberryPi to Arduino) How to Wire & Code

Hi All, Today I'm going through how to wire up and use a basic code to send a signal from a RaspberryPi to an Arduino using the I2C Method

This is a good stepping stone for communication between the 2 development boards, which I will extend on to a point of getting data transmitted from one unit to the other, which is a requirement for the Co2 Algae Scrubber project, Which you can check out here:

Grab the I2C code here on my Github for the RaspberryPi and Arduino :

For more info on I2C check out the Wiki page:

Thanks for this! I used this a few months ago to create a golf bag that shoots out your golf clubs. It's on my channel and I brought it to England to collab with Rick Shiels, the biggest golf YouTuber. All possible thanks to this video :)

Hi Scotty, thank you very much for this awesome guide. I am going to try it!

salut, s'ils vous plait comment communiquer deux esp32 via i2c et afficher sur écran LCD ??

[anonymousperson]

The two boards are powered separately right?

Hey sir, I have some problems, may you help me?
