Introduction

We are the first year students studying Computer Science in Innopolis University and we would like to share our experience in developing a Verilog program to create the coolest (well, at least, the loudest) rotary encoder ever on an FPGA board.

In this article, you will find a wonderful story about our project, the hardware, software we used and some background theory regarding rotary encoder and creating sounds in FPGA’s buzzer. Finally, we will provide a link to a github repository where a reader can access the source code. We hope you will like the project and it will inspire you to make something similar.
So, let’s start!
