This allows connection to your Arduino (or other microcontroller ... Using the LCD backpack, desired data can be displayed on the LCD through the I2C bus. In principle, such backpacks are built aorund ...

All that is needed is to connect the I2C pins of the microcontrollers and provide each with power. This project uses an Arduino as the controller and an arbitrary number of smaller ATtiny85 ...

By using a protocol called Inter-Integrated Circuit (I2C), the Wire library greatly reduces the number of wires required to connect devices. The protocol is supported on all Arduino boards ...

Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will record what is going on for a set time interval, then dump the data via serial as a .csv.
