Components Needed:
RDA5767 Module
Arduino Uno R3
Connecting Wires
Antenna (a simple wire or a dedicated FM antenna)
Breadboard (optional, for easier connections)
RDA5767 VCC to Arduino 3.3V
RDA5767 GND to Arduino GND
RDA5767 SCL to Arduino A5 (SCL)
RDA5767 SDA to Arduino A4 (SDA)
Antenna: Connect to the ANT pin on the RDA5767 module (or to the wire provided for the antenna connection).
The initRDA5767 function initializes the RDA5767 module.
The setFrequency function sets the desired FM frequency.
Adjust the frequency setting to your desired station by modifying the value in setFrequency.
Make sure the connections are secure and double-check the wiring before uploading the code. You may need to adjust the initialization and configuration registers based on your specific module's datasheet.
This basic setup will help you get started with receiving FM signals using the RDA5767 and Arduino Uno R3.
