RDA5708 FM Radio With Arduino

A FM radio with RDS info and digital volume can be made with RDA5807 module, who is similar as TEA5767 (pcb board & pins).

Step 1: Schematic & Description

This FM radio is made with:

- Arduino Uno board

- RDA5807 FM radio module

- 3 pushbuttons + 3 resistors (10kohms each)

- breadboard & shield

- more wires & USB cable

- PC speakers

Step 2: Bibliography

I found article http://full-chip.net/arduino-proekty/97-cifrovoy-... .

I tested this montage and is ok.. but I found base article is from http://seta43.hol.es/radiofm.html ...

Step 3: Tests

I test original sketch and I made some changes, first for a nice display for frequency bellow 100MHz.

In original sketch, 98.5MHz frequency is displayed 098.5MHz, after few changes value is displayed 98.5MHz, sketch is RDA5807_fmradio_3buttons_ver0.ino !

Second change is to store value for frequency and step volume in EEPROM memory, sketch is RDA5807_fmradio_3buttons_ver1.ino !

On display you can see:

- lelvel strengh signal

- if transmission is stereo or mono

- what you can made: AUTO SEARCH, INFO, MANUAL SEARCH & VOLUME

- RDS info (static and scrolling texts)

Step 4: Video Presentation

In video from https://youtu.be/10yoYn27goE you can see all components and how works... with nice presentation for frequency bellow 100MHz (sketch is RDA5807_fmradio_3buttons_ver0.ino

For finally version with last frequency of radio station and step volume stored in EEPROM memory of uC from Arduino board, see video from https://youtu.be/DEBSTJXznAw (updated sketch is RDA5807_fmradio_3buttons_ver1.ino)

I need some help with the push buttons.

I would need a schematic , because i do not understand how to solder it together :(

Somebody?????

[niq_ro]

schematic is in article... study and study... is project easy if you 'know' some electronic, must have some experience....

[Lacybad]

Solved it after 2 days. Radio is perfect :)

Thank you so much niq_ro

What do you think of Silicon Labs' Si4730? I'd like to do an AM radio recorder application, but not sure if the digital interface to get the data is capable of being done on an arduino!

I don't tested Si4730 yet... when I will buy I will test, but now I have no ideea...

Nice looking!Really thinking in making it .Already got the screen, gotta get the chip from china I guess.

Great ible!

Awesome DIY radio! A wooden case would really bring it together.

[niq_ro]

yes, a wooden case works fine with this radio, I'll try to find an old radio for case...
