It then moves on to AVR territory showing how to setup the I 2 C in an AtMega micro controller. The author uses a pretty standard to most of us Arduino, with software written in AVR C and a nifty ...

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.

[hesam.moshiri] uses a TEA5767 FM chip because of its ability to communicate over I2C. He also integrated a 3W amplifier into this build, and everything is controlled by an Arduino including a ...
