New Arduino tutorial: interface a Si7021 module

The most observant of you guys might have noticed that there’s a new tutorial available from the menu: how to interface a Si7021 humidity and temperature sensor with Arduino.

I went all in with this one, going deep enough to create my own library which supports all features of this chip!

Si7021 module pinout. The chip covered by a white protective sticker is actually the Si7021 itself.
