ESP32 Internet Radio Update

In this ESP32 project video I am going to show you the updated version of the ESP32 Internet radio. Let's get started!

A few weeks ago, I built this Internet radio device using an ESP32 board and an MP3 decoder module. You can check the detailed video of this project by clicking on the card here.
The project was working great but there were a couple of issues that were bothering me. First of all, I was not satisfied with the sound. There was a lot of noise in the audio signal.

The noise is very loud. After searching for a solution a discovered that the problem can be solved with a 50 cent part, an Isolation Transformer, this little part here. You can find a link it in the description of the video below.
A transformer is an electrical device that allows an AC input signal (like audio) to produce a related AC output signal without the input and output being physically connected together. The isolation transformer has the same number of windings on each coil. As the impedance is identical for the primary and secondary coil, the signal level does not change, so it allows an audio signal to pass unmodified from the primary to the secondary coil while blocking DC voltage and radio frequency interference. That's it! Goodbye noise!
