Here we teach our FPGA how to play sounds and music.
We start by generating a single tone. Then we slowly move on to more fun stuff, like producing a police siren and playing a tune.

You can listen to the sound produced by clicking on the speaker icon. For example here's the "police siren" .

The hardware

A Pluto FPGA board, a speaker and a 1KΩ resistor are used for this project.

A more formal representation looks like this:

The oscillator provides a fixed frequency to the FPGA. The FPGA divides the fixed frequency to drive an IO. The IO is connected to a speaker through the 1KΩ resistor. By changing the IO frequency, the FPGA produces different sounds.

The music box project is split into four parts:

1. Simple beeps
2. Sirens
3. Notes
4. Tune
