Introduction: 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.

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!

Tips

Questions

Can anyone help me out with the schematic with class d audio amp

60 Comments

are there any possibility to work without the MCP4151???

Yup, just remove that chip and put a potentiometer instead.

what about an cheaper IC? is there something?

Can you make a circuit WITHOUT the amplifier?

I would be nice if you could post also the Eagle circuit schematic since you already provided all other files :-)

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

in step 3 can you tell which software you use for making the schematic?
