I2C example

Darko:

The only thing is this is all for Arduino because @Brett says that “its unusual to want to be an I2C slave device” which I find odd because the Arduino has this built-in in the IDE.

In I2C I beleive there is always one master and one or more slaves so I would say it is more common to want to be the slave

My point is that you buy an I2C chip that does what you want. That is the slave. Your controller is the master, it tells the slaves what to do. You want an LED controller? Buy an I2C one. You want a relay control? Buy an I2C module.
