Make Your Own FM Radio

In this project I will show you how to transform a TEA5767 and an Arduino Pro Mini into a functional and decent looking FM Radio through the help of a couple complementary parts. Let's get started!

Step 1: Watch the Videos!

The two video parts should give you an overview of what is necessary to build the radio. In the following steps I will present you more detailed information.

Step 2: Order Your Parts!

Here you can find a parts list for the electronics with example sellers for your convenience (affiliate links).

Step 3: Create the Circuit!

Use the given schematic to create the circuit. It is always a good idea to wire up the components on a breadboard before moving the circuit over to a perfboard.

Step 4: Upload the Code!

Here you can find the Arduino Code you need to upload before the radio can function properly.

Step 5: Build Your Case!

Here you can find the vector graphics I made for my own case. Feel free to use them to mill your own one or print them out and use them as a template. After your case is complete it is time to mount all your other external components and main perfboard inside it.

Step 6: Success!

You did it. You just built your own FM Radio!

Hey, what are the voltage values ​​of the capacitors

[sdrahul]

Can you please upload a schematic diagram with pam8403 module or just tell me the changes in connections .Anyways a really great project the case is fabulous

[eastgoals]

If you made with pam8403 can you please share the schematic for it? Thank you.

[srishtik111]

Can you upload a circuit diagram of this project using PAM 8403 Audio amp. Pleass

[eastgoals]

If you made with pam8403 can you please share the schematic for it? Thank you.

[JohnS61]

I built this circuit on a breadboard, got it mostly working, but there is a LOT of static noise and screeching sounds. Is it because I have it wired to a breadboard? Or is it because of electrical noise coming from different parts? If I use a PAM8403 on the breadboard will it work well? Also please provide wiring schematic for PAM8403. Thanks

[eastgoals]

If you made with pam8403 can you please share the schematic for it? Thank you.

[IanChim07]

May I ask, how do you remove the static noise from the radio? I am using a lm386 audio amplifier instead of a class D amplifier, is that why I am getting a major static noise from my radio? However, if I hold the antenna, the sound becomes clearer. Please help me.

[GireeshM]

Extend the antenna on modify that to a telescopic one

[awittscience]

This is a really cool project, and it has so far been a great introduction for me to hardware. While building the circuit, I learned how to use breadboard, how to follow a circuit schematic, how to program on Arduino, and how to solder. As of now, I have the board all rigged up with the code running, but I get periodic chirps from the loud speaker as opposed to music. Initially, I though this might be due to my makeshift antenna not being long enough. However, extending the antenna did not fix the problem. Could you advise on how to finish the last stage and receive radio music instead of chirps? I would be very appreciative.

[o.akbulut1713]

Hello, 5 buttons to add the user wants to memorize the frequencies will be much better. Or turn off the radio and start the last listened frequency. Can you do?

[fanzl]

Use EEPROM library to store and read values

[sanwer solanki]

we are making this fm radio project using arduino pro mini .we need the pcb layout of the circuit to complete our project .please provide us the pcb layout

[tanmay01]

Can i get the PCB lay out i can not understood the S2 (P1, P20) portion

[denman12]

Did you receive the pcb layout?

[GireeshM]

Those who need clear Schematic diagram, please click the link

[o.akbulut1713]

i set up the fm channel and volume and when i turn off and turn on again it is not starting from my last settings i mean its not keeping it in it's memory how can i fix it , please help.

[Matthew37EDA]

Would the circuit work on 5 volts and if so how much current would it draw?

[edadams]

Got it mostly working, but for some reason it is constantly switching between modes (freq and volume)... I've tried different Arduinos and various hardware debounce techniques. Any ideas?

[edadams]

Got it figured out... oddly enough it was the way I was powering my arduino. When powered via wall-wart or usb it caused a jumpy mode switch. Powered by battery or my bench supply it's smooth as glass.
