Welcome to the Bold Inventions website!
The main focus of Bold Inventions is hobby electronics and science.
To learn about how to use I2C in your projects, we have articles about how it works, and example source code which can be adapted to almost any CPU here.
For science stuff, check out our discussion of the Tsunami Simulator. And still more on that experiment, including the slow-motion two-fluid wave machine with lots of video, check out this page.
