CHAPTER 12
FM Radio Receiver
This project uses a very low-cost FM radio module and an Adafruit LED display module to make a simple FM radio receiver (Figure 12-1).

Predefined stations are stored in the sketch, and a push-button switch is used to change stations. You also could easily modify the sketch to change channels using serial commands. This project uses an audio jack to output the received stereo signal. This will then need amplifying by connecting it to powered speakers.
