Arduino Radio

This is the code portion for an arduino-based radio, complete with a bluetoth or any similar desired modules.

User input:

The project uses a simple rotary encoder for frequency and input adjustments, the ClickEncoder library was used to greatly simplify the implementation, see: 0xPIT/encoder for more details.

Sound Input:

For FM connectivity the project uses the incredibly cheap and ever useful TEA5767 radio chip, available at just a google search away.

For bluetooth connectivity the project uses a simple bluetooth module, I got mine from ebay for about $5, it has a USB on one end and a 3.5mm jack on the other. Any module with matching description will do.

An auxilary jack is also very easy to integrate, since

Other Parts:

1. DIY arduino (any arduino will do):
   • Atmega328P
   • 16mhz oscillator
   • Button and light for basic I/O
2. Rotary Encoder
3. PAM8403 audio amplifier
4. TEA5767 radio chip
5. wire, solder, resistors, header pins, ect.

Schematics and build log to come.
