I2C or Inter-Integrated Circuit, is a really handy communication protocol that can be used to connect over 100 devices together with only 2 wires! In this video we will dive into that a little by taking a look at the uses of I2C, how to wire up multiple I2C devices, and taking a look at an I2C OLED module, an incredibly helpful device that can be added to any project.

Fantastic video! I'm completely new to microelectronics & embedded systems and this video was super easy to follow. Thanks so much for making it :-)
Excellent comprehensive tutorial, in an easy to understand format.
Another great tutorial! I assume, since there is a bus 0 and a bus 1 on the Pico, you could have two I2C devices on the Pico with the same address as long as they are not connected to the same bus.
Yes! 100% correct!
Well done, isn't I2C amazing, makes using peripherals so easy? Thank you
I don't know what I'd do without it nowadays 😁
Need multiple oleds but address is fixed, convert the i2c pins to serial (destroy link to pico i2c), and make the new i2c using other pins and write to it, again use the latest pins for serial and ...,
the pico is so fast and disconnecting from oled1 does not wipe the text on it while talking to oled2, tested with 4 oleds.
or from machine import SoftI2C using SoftI2C to create many i2c objects
tip : 400000 use 400_000 much more readable
