Last time, I gave you an overview of what you get from I2C, basics like addressing, interface speeds, and a breakdown of pullups. Today, let’s continue looking into I2C capabilities and ...

The I2C/TWI pins on the Micro are on D2 and D3. For Arduino beginners, these two boards are nearly interchangeable, especially when used in simple circuits like the Arduino's built-in examples.

Hooking up I2C sensors is something which is generally associated with microcontrollers and SBCs, yet it’s very easy to use such I2C sensors from basically any system that runs Linux.
