//Create a serial connection
Serial.begin(9600);
//Initialize the radio to the FM mode (Possible modes are AM, FM, S
W, LW).

The setup and initialization is pretty easy. We start by including the Si4703 and Wire
libraries. The Wire library is needed for I2C communication, which is what is used to
talk to the radio receiver. The Si4703 library has the functions we need to control the
radio receiver. Next we create a variable (or instance) of the Si4703 library called
‘radio.’ In the setup section all we do is create a serial connection, and use the ‘begin’
function of the radio library to initialize the Si4703. Finally we tell the Si4703 to tune to
97.3 MHz. Once things are set up, we get into the loop routine which handles the
serial communication and sending commands to the Si4703.
