Ever wanted to build an FM radio? Armed with an Arduino and a RDA5807M FM radio module, T. K. Hareendran shows us how to get started.

He put it all together on proto-board, although soldering the FM radio module was a bit tricky. The Arduino code is quite simple, and available for download (zip file).

The radio takes serial (I2C) commands, and the Arduino converts the user interface so that you can control it. The chip comes in several flavors, each with slightly different features.

That is capable of enabling your Arduino project to communicate with people and things using amateur radio bands.

The Rapid Radio is a 2.4GHz ISM band devices and is both Raspberry Pi And Arduino compatible and is supplied with full rapidradio source ...
