In this video I will show you how I took a boring flask filled with ferrofluid and turned it into a music reactive goo. For that I will be using an Arduino and an MSGEQ7 IC which determines the strength of the frequency bands in our music. This way the Arduino will know how much bass, middle and high frequencies there are and thus not only turn on LEDs according to the beat but also electromagnets which will move our ferrofluid. Let's get started!
