Modding A Pac-man Retro Light With Arduino

About the project

I'm modding nice Retro Pacman Light with an Arduino Nano to improve its functionality and effects including sound to light.

Items used in this project

So I've had this Pacman light for some time, but I don't really like the functionality it has. The main one being the sound to light effect requires the volume to be far too loud before it reacts,

In this video I show how the controller inside can be replaced with an Arduino, and then we re-program it to contain all the original effects and many more. The included code shows how to make a sound-to-light product that can even react to different sound frequencies.
