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!

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.

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

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.

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

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.

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