Making Ferrofluid Dance to the Music!

By Marco Ventimiglia on February 23, 2022

In this project we will see how to create an audio spectrum analyzer using a ferromagnetic liquid from a bottle filled with this particular liquid.

To do this, an Arduino Nano will be used and an MSGEQ7 integrated circuit that allows you to read the audio peak of a given band. In this way the Arduino will know how many low, medium and high frequencies there are and therefore not only will turn on the LEDs based on the beat but also the electromagnets that will move our ferromagnetic liquid, through the use of Mosfets.
